A computer virus is a program that is infectious and can be highly complex. Viruses implant instructions in other programs or storage devices that can attack, scramble, or erase computer data. The destructiveness of computer viruses lies in their ability to replicate themselves and spread from system to system. Few computing systems seem to be immune to infection. There are two categories of viruses that are common today: macro viruses and worms. Computer viruses are never "naturally occurring"; they are always man-made. Once created and released, however, their spread is not directly under human control.

CaTS now requires that all computers connected to the university network have virus scanning software installed. You can download McAfee VShield (Windows) and McAfee Virex (Macintosh) free of charge from the CaTS Anti-virus Software website. Note: If you're using a CaTS supported computer on campus (contact the Help Desk at 775-4827 if you're not sure), antivirus software will be installed automatically for you on that computer.

The following activities are among the most common ways of getting computer viruses. Minimizing the frequency of these activities will reduce your risk of getting a computer virus.
