Become High Performance Computer

Passwords are the keys we use to access personal information that we have stored on our computers and in our online accounts.

If criminals or other malicious users steal this information, they can use our name to open new credit card accounts, apply for a mortgage, or pose as us in online transactions. In many cases we would not notice these attacks until it was too late.

Fortunately, it is not hard to create strong passwords and keep them well protected.

What makes a strong password ?

To an attacker, a strong password should appear to be a random string of characters. The following criteria can help your passwords do so:

Make it lengthy. Each character that you add to your password increases the protection that it provides many times over. Your passwords should be around 8 or more characters in length; 12 characters or longer is ideal.

Many systems also support use of the space bar in passwords, so you can create a phrase made of many words (a "pass phrase"). A pass phrase is often easier to remember than a little password, as well as longer and harder to guess.

Combine letters, numbers, and symbols. The greater variety of characters that you have in your password, the harder it is to guess. Other important specifics include:

• The fewer types of characters in your password, the longer it must be. A 15-character password composed only of random letters and numbers is about 33,000 times stronger than an 8-character password composed of characters from the entire keyboard. If you cannot create a password that contains symbols, you need to make it considerably longer to get the same degree of protection. An ideal password combines both length and different types of symbols.

• Use the entire keyboard, not just the most common characters. Symbols typed by holding down the "Shift" key and typing a number are very common in passwords. Your password will be much stronger if you choose from all the symbols on the keyboard, including punctuation marks not on the upper row of the keyboard, and any symbols unique to your language.

Use words and phrases that are easy to remember, but difficult for others to figure out. The easiest way to remember passwords and pass phrases is to write them down. Contrary to popular belief, there is nothing wrong with writing passwords down, but they need to be adequately protected in order to remain secure and effective.

In general, passwords written on a piece of paper are more difficult to compromise across the Internet than a password manager, Web site, or other software-based storage tool, such as password managers.

Create a strong, memorable password in 6 steps

Use these steps to develop a strong password:

1. Think of a sentence that you can remember. This will be the basis of your strong password or pass phrase. Use a memorable sentence, such as "My cats three years old."

2. Check if the computer or online system supports the pass phrase directly. If you can use a pass phrase (with spaces between characters) on your computer or online system, do so.

3. If the computer or online system does not support pass phrases, convert it to a password. Take the first letter of each word of the sentence that you've created to create a new, nonsensical word. Using the example above, you'd get: "mctyo".

4. Add complexity by mixing uppercase and lowercase letters and numbers. It is valuable to use some letter swapping or misspellings as well. For instance, in the pass phrase above, consider misspelling Aiden's name, or substituting the word "three" for the number 3. There are many possible substitutions, and the longer the sentence, the more complex your password can be. Your pass phrase might become "My cATs THreE YeaRs olD." If the computer or online system will not support a pass phrase, use the same technique on the shorter password. This might yield a password like "McTyo".

5. Finally, substitute some special characters. You can use symbols that look like letters, combine words (remove spaces) and other ways to make the password more complex. Using these tricks, we create a pass phrase of "MycAT i$ 3 yeAR$ old" or a password (using the first letter of each word) "Mci3y0".

6. Test your new password with Password Checker .Password Checker is a non-recording feature on this Web site that helps determine your password's strength as you type.

Password strategies to avoid

Some common methods used to create passwords are easy to guess by criminals. To avoid weak, easy-to-guess passwords:

• Avoid your login name. Any part of your name, birthday, social security number, or similar information for your loved ones constitutes a bad password choice. This is one of the first things criminals will try.

• Avoid dictionary words in any language. Criminals use sophisticated tools that can rapidly guess passwords that are based on words in multiple dictionaries, including words spelled backwards, common misspellings, and substitutions. This includes all sorts of profanity and any word you would not say in front of your kids.

• Use more than one password everywhere. If any one of the computers or online systems using this password is compromised, all of your other information protected by that password should be considered compromised as well. It is critical to use different passwords for different systems.

• Avoid using online storage. If malicious users find these passwords stored online or on a networked computer, they have access to all your information.

The "blank password" option

A blank password (no password at all) on your account is more secure than a weak password such as "1234". Criminals can easily guess a simplistic password, but on computers using Windows XP, an account without a password cannot be accessed remotely by means such as a network or the Internet. (This option is not available for Microsoft Windows 2000, Windows Me, or earlier versions) You can choose to use a blank password on your computer account if these criteria are met:

• You only have one computer or you have several computers but you do not need to access information on one computer from another one

• The computer is physically secure (you trust everyone who has physical access to the computer)

The use of a blank password is not always a good idea. For example, a laptop computer that you take with you is probably not physically secure, so it's better on those to have a strong password.

How to access and change your passwords

Online accounts

Web sites have a variety of policies that govern how you can access your account and change your password. Look for a link (such as "my account") somewhere on the site's home page that goes to a special area of the site that allows password and account management.

Computer passwords

The Help files for your computer operating system will usually provide information about how to create, modify, and access password-protected user accounts, as well as how to require password protection upon startup of your computer. You can also try to find this information online at the software manufacturer's Web site. For example, if you use Microsoft Windows XP, online help can show you how to manage passwords, change passwords, and more.

Keep your passwords secret

Treat your passwords and pass phrases with as much care as the information that they protect.

• Don't reveal them to others.

• Protect any recorded passwords. Be careful where you store the passwords that you record or write down.

• Never provide your password over e-mail or based on an e-mail request. Any e-mail that requests your password or requests that you to go to a Web site to verify your password is almost certainly a fraud.

• Change your passwords regularly. This can help keep criminals and other malicious users unaware.

• Do not type passwords on computers that you do not control. Computers such as those in Internet cafés, computer labs, shared systems, kiosk systems, conferences, and airport lounges should be considered unsafe.

What to do if your password is stolen

Be sure to monitor all the information you protect with your passwords, such as your monthly financial statements, credit reports, online shopping accounts, and so on. Strong, memorable passwords can help protect you against fraud and identity theft, but there are no guarantees. No matter how strong your password is, if someone breaks into the system that stores it, they will have your password. If you notice any suspicious activity that could indicate that someone has accessed your information, notify authorities as quickly as you can.

As of this time, let me elaborate more on the computer optimisation tips that they provide to their computer rental customers.

To keep the computer running smoothly and efficiently, computer maintenance must always be performed regularly. You should check your computer hard drive memory if there is enough free space. The more files loaded in the computer memory, the slower it will run. It is said that 20-25% free space availability of hard disk memory is the limit to keep maximize computer speed and to have it work properly. You should not forget to perform memory checking at least once every month. This way, you would be able to know if it's time to delete unnecessary files stored in your hard disk.

One of the reasons why the computer's performance is getting bad is the virus. It makes the computer speed slower and worse, damages your computer in the long run if taken for granted. It is recommended to install antivirus software to keep your computer safe. Viruses are great computer hard disk destroyer, as much as worms. Worms do not directly damage your computer; however, they are duplicating the files, the filename as much as the file size. As a result, your computer memory gets crowded, causing your computer to perform badly. Before everything turns bad, install antivirus that is proven effective right away after buying your computer and opening it for the first time. You can choose from AVG, Bitfender, Avira and other antivirus software brands. Antivirus software applications do not only protect you from computer viruses and worms, but also from various forms of spywares. Scan your computer for viruses, ideally, twice a month.

Spywares are sometimes undetectable by spyware blocker installed together with antivirus program. Installing a separate spyware application may be of help to keep your computer safe from bad people who want to gain remote access of your computer.

You should also check your computer registry. The errors in computer registry also can damage your computer if not given attention and not fixed immediately. Running a registry repair software programs is a big help. Through them, the errors in the computer registry are fixed thoroughly, making your computer to run smoothly and efficiently once again.

Defragmenting the hard disk may not be needed. However, performing it once a month can boost PC performance. Files that are scattered in the hard disk are organized through defragmenting. If the files are organized in the hard disk, computers can access the data easily. This avoids wears on the read heads of the hard disks; wears can eventually damage the hard disk.

If the tips being mentioned here are followed and done in a convenient frequency, you will see that your computer performance gets better.

So you're thinking of buying a new computer...

Where do you start? There are so many brands and models of computers available, and it can all be a little overwhelming when you start to look around.

How do you decide what type of computer you need? And perhaps more importantly, how do you decide what the best value is?

1. Buy What You Need, Maybe a Little More

One of the most important things you can do when buying a new computer is make a list of the things that you will be using it for. There are so many different models - with different capabilities - that you can easily buy more, or less, than you really need if you don't.

If this is your first computer, this can be a little tougher. Until you've used a computer, it's hard to know exactly what you might want to do with it beyond the obvious, like connecting to the internet.

Regardless, you should think about some of the things you might want to do. Some possibilities include:

* Connect to the internet
* Play games
* Digital photography
* Digital video
* Type documents
* Accounting
* Design websites
* Programming
* Digital scrapbooking
* Geneology

Some of these things need more power than others. For example, connecting to the internet really doesn't need a lot of power. Even the most basic computer available will probably work just fine.

Digital video and many games need a lot more power. If you don't get a fast enough computer with enough memory, you'll be disappointed with the performance.

Knowing what you're going to be using your computer for will help your salesperson, whether they're on the phone, the internet or standing in front of you, recommend the best system for your needs.

As a general rule you're always better off buying more power than you need rather than less, but buying too much can be a waste of money.

2. Warranty Considerations

Computer warranties are one of the most confusing and obscure parts of your purchase. Most manufacturers have cut back on their customer service to the point where poor service has become a given.

The three most common options are onsite, carry-in or manufacturer's depot service.

Onsite service can be helpful, but think about whether you want to have to be available for a technician to come and diagnose your computer, and possibly have to come back with parts at another time.

Carry in service is a good option, but find out whether the service center is factory authorized for warranty repairs, as well as whether the technicians are all certified.

Shipping your computer to a factory service center can take a long time - sometimes a number of weeks. It also creates risk that your computer will be damaged or even lost in shipping. In some cases, the manufacturer will even replace your computer with another unit and ship it back to you, rather than repairing it. This can result in your losing any information that was on your system and having to reload all your software.

Another aspect of the warranty to find out about is technical support. Find out if the computer manufacturer offers a toll-free phone number and what the quality of service is like.

The better computer salespeople will be honest about this and tell you if a company's service leaves something to be desired. You can also do some research on the internet - most of the computer magazines like PC Magazine and PC World have annual customer service comparisons that rate the larger computer companies.

Always find out how the warranty is handled before making your decision. Even if it doesn't influence your choice, knowing what to expect if something does go wrong will save some nasty surprises down the road.

3. Can You Negotiate the Price Down?

A computer is a relatively large investment - anywhere from a few hundred to a few thousand dollars. Many computer buyers expect that there is a significant amount of "wiggle room" on the price.

The reality is that most computer hardware - the physical pieces like the computer, monitor and printer - is sold at very low profit margins. Often, computer systems are even sold at or below the dealer cost. When you're buying a computer, it never hurts to ask for a better deal, but don't be surprised if you only get a few dollars off, if anything.

What you can do to get the best price is to do some comparison shopping. Most computer stores offer price-matching guarantees, so if you find your computer for less at another store, most dealers will match or beat that price, even if it means they lose money.

4. What Software is Included?

The last secret of buying a new computer has to do with the software that is included. Most new computer systems include quite a few programs and sometimes the value of the software can be quite high.

Something to watch out for when looking at the included software is "trial versions" or "limited editions".

Many programs that are preloaded are either crippled versions that don't have all the features of the full program, or trial versions that will only run for a certain amount of time before they expire.

Computer are often sold with trial versions of the following types of software:

* antivirus
* firewall
* MS Office or other office suites
* Accounting - both business and personal

The computer manufacturers generally don't make it easy to tell whether the software on their systems are trial versions or limited versions. This is a question that you should specifically ask if you can't find the answer in their promotional information.

If you're buying a new computer with trial versions of the software, keep in mind that you will need to pay to continue using it after the trial period is over. This is an added cost that you need to consider as part of your overall budget.

These five "secrets" of buying a new computer are fairly common sense, but they are not always made clear up front. Knowing what to ask will help you in two ways. First, you can be sure you are getting the right computer for your needs.

Second, if the salesperson or company that you're dealing with explains these things to you without being asked, you'll know you're dealing with someone who is honest and upfront.

Knowing you can trust the people you're dealing with is an invaluable feature of your new computer system.

Here are a couple of tips to speed up your Windows XP computer and help keep you protected and secure online. First you need to control which programs load on startup: Many of the programs you install on your computer automatically configure themselves to launch at startup, usually invisibly. The truly essential ones, such as anti-virus and firewall products, generally run as services and run fine in the background. Other less important software like media players don't need to be running continually.

These extra programs slow the boot process and then severely suck up resources like memory and CPU cycles. It is pretty easy to control which applications launch on startup. The System Configuration Utility lists all these applications in one place:

1) To get there: Click the ‘Start' button then choose the ‘Run' command.

2) In the text box type "msconfig". - Across the top of the dialog box select the ‘Startup' tab.

3) The Startup Tab lists all the programs that launch at start-up. To disable any of these simply un-check the box on the left. Only non-essential programs are listed here it should be safe to un-check pretty much anything. If it turns out you needed it just go back and re-check it.

4) Once you are done re-boot the machine. 5) When the Desktop returns you will be presented with a window that says you have chosen Selective Startup. Just Check "Do not show this window again" and click OK.

To keep your computer secure, turn on automatic updates. Seems like every virus writer has nothing better to do then attack Windows operating systems. Keeping the system patches and security fixes is critical. During the setup of XP Service Pack 2 with a new computer or an up-grade you are asked whether or not to turn on automatic updates, if you made the mistake of checking no you can find this option in the Windows Security Center (Start / Control Panel) and change it back. Even with all its faults, XP is a powerful operating system that has many good security features.

Here are some more tips to help you get the most out of your operating system. Remove Windows components not found in ADD / REMOVE. Many Windows components, things like Network Services or Solitaire are easy to remove through the Add or Remove programs configuration window (Start / ControlPanel / Add and Remove Programs / Windows Components). Simply un-check them, but … some things are deliberately hidden.

A good example would be MSN Messenger. To remove this from startup follow these steps:

1) In Windows Explorer (right click Start / Explore), navigate to C:WindowsInf and make a copy of Sysoc.inf.

2) Double click on Sysoc.inf and it will open in Notepad.

3) Press Ctrl H (opens Find and Replace) and replace the string ,hide, with ,, then save and replace the file. Now all the hidden components will appear.

4) Then follow the steps above for removing programs from the startup menu.

To restore a corrupted system file: If a necessary system file should become missing or corrupted by a virus you can replace it from your Windows CD.

1) Go to Start / Search and type in the file name replacing the last letter with an underscore (ex. Filename.ex_).

2) If the file is found, open a command prompt (Start / Run, type CMD in the textbox).

3) At the prompt type expand followed by the full pathname of the file and destination (expand D:Windowsfilename.ex_ C:Windowsfilename.exe) where D: is the letter of your disc drive. If either pathname contains spaces surround the entire pathname with double quotes. If the file isn't found search again using the un-modified file name, it is probably in a CAB file, Windows treats these as folders, simply drag the new folder to the destination while holding down the right mouse button then select Copy Here.

The last few years have witnessed some exhilarating developments in the manufacturing of hard drives with the introduction of larger caches, quicker spindle speeds, greater data transmission speeds, and better reliability.

ATA hard drives (generally known an IDE drives) are the hard drive type mainly used by most end user computers.

Introduced in 1986, the ATA standard has seen many modifications to improve the size and speed of the hard drive which it can support. ATA-7, unleashed in 2001, can maintain data transfer rates up 133MB/sec.ATA-7 is thought to be the last model for the parallel ATA standard.

In the year 2000, hard drive manufacturers came up with a new hard drive standard called Serial ATA, most popularly SATA. The SATA hard drives overcame all the limitation of ATA such as electromagnetic interference (EMI), signal timing, and other data integrity issues. Within no time, SATA has become the basic standard for most computer users.

The following description elaborates on the differences between ATA and SATA.

Advanced Technology Attachment (ATA) is based on a 16 bit parallel interface and is generally used to control computer hard drives. Whereas, Serial Advanced Technology Attachment (SATA) is a single bit serial advancement of the Parallel ATA. SATA hard drives can easily be distinguished from ATA hard drives by the unique power and data connections used on the back of the hard drives.

When comparing ATA against SATA, SATA hard drives have performance benefits which set them apart from ATA hard drives. SATA drives are more suitable to install and draws less power. Another noted characteristic of SATA is the higher bandwidth that is possible. The latest models of ATA hard drives offer the highest data transfer rate of 133 MB/second. While the current SATA standard can provide data transfer of up to 150 MB/second.

According to Seagate, the performance of SATA drives over ATA drives can currently be expected to be about 5%. The developments in SATA technology will surely improve on that. The future of SATA bears great interest in computer users, the 600 MB/second SATA hard drives are expected around the year 2007, which will provide outstanding speed and performance.

When making a comparison of ATA hard drives and SATA hard drives, you may find SATA drives to cost more, but when considering the overall benefits of SATA drives over ATAs, it is worth spending a few extra dollars for SATA hard drives.

In short, the latest SATA hard drives provide noteworthy benefits over ATA hard drives when considering power consumption, convenience, and performance. Experts are in the process of creating more powerful SATA hard drives which will surely help hard drive developments to keep pace with other key system products to improve the overall performance of a computer system.

The most popular and probably the easiest upgrade project for PC enthusiasts is still installation of a new hard drive. It's just a matter of time before terabyte-eating applications demands an upgrade to a bigger and faster hard drive. And don't forget video, audio and graphic files. There are several sizes to choose from and certainly all price ranges.

Most drives come in 5400 and 7200-rpm versions. The 5400-rpm drives are less expensive than the 7200-rpm models, but you will then loose the performance boost delivered from the 7200 version. If you need quicker access times and improved data transfers, the 7200 version is a better alternative.

You should plan to make your new drive your primary drive i.e. the new home for your OS. This simply because your new hard drive is bigger and faster. The old drive may be your secondary hard disk and you may use it for archives etc.

All major drive makers pack software with their upgrade kits that prepares the drive for partitioning and formatting and can also copy what's on your current drive to the new one, helping to make the upgrade a breeze.

1. Preparation of PC

Prepare Your PC's existing Hard Drive from future problems. Make sure the current drive in your PC is trouble-free.

Run ScanDisk followed by the Disk Defragmenter. These tests could take hours to complete but you will save time and headaches later in the installation process by ensuring that you will be copying error-free data.

Do not forget to make backup of your hard drive ie if you are able to. Don't forget files like normal.dot from Microsoft Word and Bookmarks or Favorites from your Web browser.

2. Run the New Drive-Installation Software

First of all, read your new hard drive's manual. Almost all hard drives ship with installation software that takes care of formatting and partitioning. Some will even help you transfer data from your old disk to the new one. You must run most installation software before you physically install the new drive. You will either install and run the software from within Windows, or boot from a floppy disk. Program details vary by drive manufacturer, so read the directions carefully.

3. Open your PC

Turn off your computer and unplug it before you remove the cover. Before you begin working inside your PC, put on an antistatic wrist strap. You can get this from local electronics supply stores. Clip it to a grounded metal object.

A. Find a space. Usually you will find an accessible space for your new hard drive next to your existing drive.

B. Find the drive. Make a note of where the red wire of the cable meets the drive (Pin 1) so you can connect your new cable correctly. Mark the location with masking tape.

C. Find a power connector. Alternatively you need a y-adapter if your power supply has no free connector.

D. Use your new cable. For best performance, today’s drives require an 80-wire cable. Most drives ship with one. Replace the old with the new one, the connectors are compatible.

4. Set the Drive Jumpers.

It's advisable to install your new drive as the second drive on the primary IDE channel. This is exactly the same channel where the current drive is connected. When two IDE drives are connected to a single cable, one must be designated 'Master', and the other 'Slave'.

These jumper settings should be printed on the drives. Set your new disk as your PC's boot drive, and its jumper to Master. Change the jumper settings on your old drive to Slave. Check that the installation software supports copying of data over to your new hard disk.

5. Assembling

Install the new drive. Attach the two connectors on the new ribbon cable to both your hard disks. Make sure the red wire goes to Pin 1. Also make sure the other end of the cable is connected to the primary IDE connector on the motherboard, and that it's correctly connected so that the red wire on the cable goes to Pin 1 on the motherboard connector.

Power up both drives. Check all your connections. Don't put the cover back on until you're sure that everything's working correctly.

6. Finishing up

Put your installation utility disk is in the floppy drive. Turn your PC on. Enter your PC's setup utility. This is done either by pressing Delete, F1, or F2 at start-up, although details could vary by manufacturer. Make sure drives 1 and 2 are set to AUTO. If they're not, your PC may not detect your new drive.

Save the setup settings. Reboot from the installation utility floppy disk. Follow the directions to set up your new drive and copy the data from the old to the new one.

Finally, remove the floppy and reboot your PC. After this your PC should start Windows normally. After checking that everything's working, reformat your old drive to wipe out its superfluous data and to prepare it for new files.

For most entrepreneurs computers are an intrical part of our business. An entrepreneur can not afford for their computer to be inoperable even for a minute. Implement some of these quick and affordable computer tips to keep your computer healthy and making money for your business.

1 - Double Internet Speed

Comcast recently doubled cable modem download speeds. Now you can surf the Internet and download files twice as fast. However, you need to power cycle your cable modem [unplug it for 30 seconds and reboot computer] for the new configuration to be automatically downloaded to your modem.

2 - Connecting to Work from Home

Having trouble with your corporate VPN connection when working from home? Oftentimes this can be fixed with a simple firmware upgrade to your network router or a slight change in settings.

3 - Sudden Lost Connection

Has your Internet connection suddenly stopped working? Frequently computer users with software-based firewalls suddenly find their Internet connection no longer available. Oftentimes when you download a software update, it can change your original configurations. As a quick test, disable the software firewall. If connectivity returns, it’s a misconfiguration issue.

4 - Slow E-mail and Internet Browsing

Has your computer been working wonderfully, but suddenly e-mail or Internet browsing is painfully slow? It could be your cable connection went out. And although the connection has returned, your computer and the cable modem may be having difficulty communicating. Try power cycling your modem.

5 - Eliminate Popups

Google offers a free popup blocker with its toolbar. Download the toolbar at www.toolbar.google.com. System requirements: Microsoft Windows 95/98/ME/NT/2000/XP, Microsoft Internet Explorer 5.0 or later. The popup blocker requires Internet Explorer 5.5 or later.

So you’re ready to enjoy unlimited long distance calling and lower monthly phone bills. Well, before you make the switch, here are five steps that will help you get the VoIP plan that is best for you.

Make the Decision

Yes, it is new technology, and sometimes we are scared of the unknown. VoIP technology is on the rise and many high profile computer companies are already switching to VoIP and in return are becoming service providers. AOL, Sprint, and Verizon are offering VoIP as well as Internet Messaging services such as Yahoo, MSN, and AOL IM. First you must come to the decision that VoIP is best for you, your family, or your business needs. Research VoIP on the web and its providers. Talk to people that you know have already made the switch. Once you have made your decision to switch to VoIP, you are ready for the next step.

Choose the Plan that is Right for You

A good idea is to make a written list of your needs, wants, and features in a phone. This will help you compare different plans and choose the service provider that will best fit your needs. If you are looking for residential or business service, make sure that you note that in your list. Residential plans usually come in two forms- basic (which is a certain amount of minutes) and unlimited (which will give you unlimited local and long distance talk time). Business plans can include amenities such as multiple phones, greater minute talk time, greater unlimited calling plans, business features bundled with your plan, faxing and voicemail to your computer capabilities, and extras such as yellow page listings. Check with the company to find the plan that meets your requirements.

Setting up the System

Some service providers will send you the equipment that you need to begin using VoIP. You will first need to make sure that your computer system is compatible with the VoIP service. You will also need to have high speed Internet already installed with your computer. If you are using VoIP for a business or for a call center, it is best to leave the installation to a professional. Installing VoIP for a residence or home office is typically simple enough for most residents to do themselves.

Choosing your Phone Number

One of the best features that VoIP has to offer is the freedom to select your own telephone number. If you just want to transfer your old number to your new VoIP system, check with your service provider before making your final decision. Many VoIP providers will allow you to transfer your phone number.

If you want to select a different area code, this option has many advantages. First, for friends and family members who don’t have unlimited long distance calling, selecting the same area code as them can save them money. They will appreciate being able to call you as if it were a local call.

This strategy is also very beneficial for those whose businesses are targeting specific areas. Say there is a California company, yet they want to increase business in Tampa, Florida. By selecting the Tampa, Florida area code, they can increase sales and productivity by having a local number for customers to call. This also reduces the need for a toll free number.

Install your Features and Accessories

VoIP comes with many features included in your service plan. For residential customers these include Voicemail, Caller ID, Call Forwarding, Call Block, and Do Not Disturb. Always check with your service provider for a detailed listing of the features included with your plan. For Small businesses, amenities such as multi phone users, free fax lines, and integrating your VoIP and web features are all available. VoIP also contains many of the same features bundled with basic plans as well. When you are choosing a provider, compare their business plans and select the one that best fits your business needs.

As VoIP technology continues to advance, a new array of accessories appears on the market. Today you can choose from VoIP phones, headsets, and even VoIP videophones that work as a web camera incorporating video with your audio.

Problem: Malware / Adware

If Internet Explorer is behaving strangely (crashing, visiting unwanted sites, etc), it's possible that there is malicious software installed on your computer.

As a first step, you should allow your antivirus software to scan and attempt to repair your computer. Additionally, you may want to try the following Microsoft tools:

• Windows Defender
• Windows Live OneCare
• Windows Live Safety Center
• Malicious Software Removal Tool

You should also ensure your computer has all the security updates available at Microsoft Update.

Problem: My searches are redirected to unrelated sites and I cannot connect to WindowsUpdate or antivirus websites

If Internet Explorer searches are redirected to unrelated sites or search engines, it's possible that your computer was infected with malware. However, if your computer is not currently infected with malware, it's possible that at some time in the past, malicious software altered your computer's DNS settings. DNS works like an "internet phonebook" that maps URLs (like "windowsupdate.microsoft.com") to internet protocol addresses (like "207.46.225.221").

To determine if a malicious DNS server is configured:

- Go to Start -> Control Panel ->Network Connections.

- Right click your default connection, usually Local Area Connection or Dial-up Connection, if you are using Dial-up, and left click on Properties.

- Double-click on the Internet Protocol (TCP/IP) item

Check to see if you're set to something other than "Obtain DNS servers automatically". If so, contact your ISP to ensure that the address specified is correct, or set the "Obtain DNS servers automatically" checkbox. Then restart your computer.

Problem: Overlong headers result in HTTP/4xx or HTTP/5xx errors, particularly on devices like routers or webcams

Problems of this nature are usually caused by one of the two request headers in yellow being longer than the device expects.

GET / HTTP/1.1

These headers are dynamically generated out of registry keys. They can usually be trimmed by editing the registry without any important side-effects.

To trim the list in the Accept header, click START > RUN > REGEDIT.EXE. Using RegEdit, navigate to:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents

..and remove elements from the "Name/Type/Value" list to remove values that aren't strictly required. Elements in red are of lower importance than those in black:

image/gif, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, application/x-silverlight, application/x-silverlight-2-b2, */*

A similar problem can occur with the User-Agent header.

To trim the list in the User-Agent header, click START > RUN > REGEDIT.EXE. Using RegEdit, navigate to:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform
