Antivirus software is one of the most important tools for safe-guarding your computer, vital information, and personal data from the daily onslaught of viruses and worms. Without anti-virus your computer may be left completely defenseless against malicious attacks. Antivirus software is available from CABQ Service Desk and should be activated prior to the computer being put on-line.
Quick Tip: Many worms and viruses spread to a PC when web page scripts are run in your browser. These scripts typically provide interactivity on the page. You can turn off browser scripting in Internet Explorer by selecting Tools, Internet Options, Security and clicking Custom Level. Disable Download unsigned ActiveX controls, Initialize and script ActiveX controls not marked as safe, Active scripting, and Scripting of Java applets.
Update your Antivirus Regularly
Your virus protection is only as effective as its last update. New viruses appear all the time. If your antivirus software isn't current, the latest viruses or worms can sneak in. Updating anti-virus scanner definitions is a crucial part of keeping your computer safe from viruses and worms. This process will keep your scanner up-to-date, so it will be able to detect the most recent virus or worm. Antivirus automatically checks for antivirus engine updates as virus definitions are updated.
There are currently more than 50,000 viruses in existence and 200 viruses are discovered each month, it's recommended you update your software at least once a month.
Antivirus software is especially useful for scanning attachments and links within e-mail messages. E-mail offers many opportunities for security problems and should not be considered secure. Remember not to open email attachments from unsolicited sources. Malicious web sites can install software on your computer or collect personal information from your computer. Be cautious of e-mail attachments and website downloads that you do not know anything about. It is actually very easy for a computer virus to be present in e-mail from anyone, including your parents, best friends, or colleagues. It is strongly suggested that antivirus software be used to scan anything that you receive in your e-mail.
One of the main problems with viruses or worms is they can go undetected, especially if you are not running an antivirus program which would catch the intruders immediately. Below are some key signs that your computing system may be infected by a virus or worm, and what to do to solve the problem:

A virus is a computer program intentionally written and released to spread across computers and networks and disrupt your computing experience. These malicious attacks come to your PC through e-mail, the Internet, downloaded files, and files you open on a CD. Viruses typically work by attaching themselves to another program on your PC, and do not infect the computer until the program runs. The old "traditional" viruses usually require human interaction (you have to run it, save it, share it; you e-mail a program or document without knowing it's infected). Viruses typically just attach themselves to programs and documents and then depend on humans to propagate. This is changing...
A worm is similar to a program but doesn't need to attach itself to another program to run. Worms, a sub-class of viruses, are replicated automatically without human help (like an e-mail address book attack). Worms can bog down networks and web sites. And, the scary part is that you don't have to do anything but turn your computer on!
A Trojan poses as a legitimate program but is designed to disrupt computing on the PC it infects. It is not designed to spread to other computers.
This type of code allows other computer users to gain access to your computer across the Internet.
