What is a Computer Virus?

A computer virus is a program that spreads itself by infecting files. When it runs, a virus will essentially wrap a file's data in its own code. When the file is opened, the virus runs its program first and then opens the file as initially requested. Some computer viruses are malicious, erasing files or locking up systems; others merely present a problem solely through the act of infecting other code. Standard viruses will spread only when an infected file is transferred from one computer to another.

Computer worms are self-propagating and can not be considered ordinary viruses. Worms, unlike other viruses, don't infect files, but entire disks or computer systems. Because worms can't rely on file-to-file transfers to spread their code, they need to have a way of sending themselves to other computer systems and the most common way is via e-mail. Known as mass mailers due to the technique of spamming themselves to every address in the e-mail address book, such worms generally require a person's action to spread.

In either case, computer virus infections should not go untreated.

Viruses come in many shapes and sizes, such as:

File infectors
These viruses attach themselves to regular programs, such as .COM or .EXE files under DOS. Thus, they are invoked each time the infected program is run.

Cluster infectors
They modify the file system so that they are run prior to other programs. Note that, unlike file infectors, they do not actually attach themselves to programs.

Macro viruses
Word processing documents can serve as sources of transmission for viruses that take advantage of the auto-execution macro capabilities in products such as Microsoft Word. Simply by opening an infected document, the virus, written in a product's macro language, can spread.

System infectors
Computer operating systems typically set aside a portion of each disk for code to boot the computer. Under DOS, this section is called a boot sector on floppies or a master boot record (MBR) for hard disks. System infectors store themselves in this area and hence are invoked whenever the disk is used to boot the system.




How do I prevent my computer from being infected by a virus?

Follow the virus detection and prevention tips listed below to lower the chances of your computer being infected by a virus:

1. Do not open any files attached to an e-mail from an unknown, suspicious or untrustworthy source. This applies to e-mail attachments sent by someone you know, unless you are aware of the contents of the attached file. Some viruses can replicate themselves and spread through e-mail.

2. Do not forward or reply to any to chain e-mails and junk e-mail. These types of e-mail are considered spam, which is unsolicited and intrusive.

3. Make sure that you have one of the anti-virus programs such as McAfee (www.mcafee.com) or Norton (www.norton.com) or AVG (www.grisoft.com) on your computer.

4. If you do not have any of the anti-virus programs, you may scan your computer (online) for any viruses for free.

5. When downloading files from the Internet, verify that an anti-virus program checks the files on the download site. If you're uncertain, don't download the file at all.

6. Update your anti-virus software regularly so that it is capable of detecting latest viruses discovered. To update your anti-virus software now, click here.

7. Update your Windows regularly to make sure that you have the critical and most updated files and programs for your system. This enhances the virus detection capability and makes virus prevention easier. To do windows update now, click here.

8. Back up your files on a regular basis. If a virus destroys your files, at least you can replace them with your back-up copy. You should store your backup copy in a separate location from your work files, one that is preferably not on your computer (e.g floppy disk).




What do I do if a virus is found in my computer?

If your computer has detected a virus, get the name of the virus and search for information on how to remove the virus.

- If you have a McAfee anti-virus program, click here.
- If you have a Norton anti-virus program, click here.
- If you have an AVG anti-virus program, go to here.




Where do I go to get the latest updates for my anti-virus software?

- If you are a McAfee user, click here.
- If you are a Norton user, click here.
- If you are an AVG user, click here.




How do I update my computer's Windows operating system?

If you are using a PC with Microsoft Windows 95/98/ME/XP/NT/2000, you may follow the instructions below for fixes, updates and enhancements to Windows and other programs that work with Windows.

1. Go to Start -> Windows Update or www.windowsupdate.microsoft.com.

2. Click on PRODUCT UPDATES link. If a "Security Warning" dialog box pops up on the screen, click on "Yes" to continue.

Windows Update scans your system to see what you have installed and gives you a list of suggested components. This scan is done on your computer to ensure the safety and privacy of your system information. This system check assures that you will get the most up-to-date and accurate versions of anything you choose to download from the site. Additionally, you won't waste time downloading components you have already installed.

3. When the list of components appears on the page, you can browse it, decide which components you want, and download them right to your computer. When you decide you want a certain component, click the box next to it. A check mark appears in the box (If you decide you don't want a product you've already selected, just click the box again to remove the check mark). Before you choose to download a component, "Read this first" link for important information.

Note: Be sure to download any critical updates recommended for your system. Critical updates will fix known problems (such as security issues) specific to your computer.

4. When you have selected all the components you want, click the "Download" button.

5. Click the "Start Download" button. All the components you selected will be downloaded, then installed. This process may take a while depending on the size of the file and your connection speed. When you see the "Installation Complete" message, you're done! Some components may require you to shut down and restart your computer after installation of all components is complete.

Important: You should do the Windows updates every so often to keep your system updated.

How to filter Internet Content through Microsoft Internet Explorer?

You can control access to online material using any PICS-based Internet ratings system. Internet Explorer includes a built-in ratings system called RSACi that lets you choose different levels of allowable language, nudity, sex, and violence. Parents or managers can also set passwords to allow access to any Web site. Plus, they can block viewers from accessing Web sites that aren't rated. Microsoft Content Advisor

What is Multilink PPP?

If you are too far from the telephone company central office to qualify for DSL or if DSL is not available in your area, Multilink PPP is a viable option. Multilink PPP enables your computer to use two or more communications ports as if they were a single port of greater bandwidth. This means that if you use two modems to connect to the Internet, you can connect at double the speed of a single modem. Multilink PPP is now supported by Windows 95, 98 and NT 4.0




What do I need for Multilink PPP?

1. An operating system that supports Multilink PPP.
- Windows NT supports Multilink PPP with a maximum of 4 modems. Service Pack 3 should be installed for better performance.
- Windows 98 supports Multilink PPP with a maximum of 4 modems. The dial-up metworking security upgrade should be installed for better performance.
- Windows 95 will support Multilink PPP with a maximum of 2 modems if the dial-up metworking 1.3 upgrade is installed.

2. Two or more phone lines.

3. CAL Internet Services Multilink PPP service.




What kind of speed can I expect with Multilink PPP?

Tests with Multilink PPP have been very promising. A speed improvement is definitely noticed. The speed achieved is equal to the number of modems times the speed of the slowest connection. For example, if Multilink PPP is used with two modems connected at 44k and 41.3k, then the achieved speed would be equivalent to 2 * 41.3k = 82.6k (faster than a single channel ISDN line!!!).




How much does Multilink PPP cost?

You will need a dial-up account for each concurrent connection. CAL Internet Services is offering a dual line connection. There are no extra set up fees to enable Multilink PPP.




What if I still have questions related to Multilink PPP?

If you have any questions, please give us a call at 1.800.953.9525 or e-mail info@calis.com.
