Virus information and protection
Computer viruses are programs intended to harm your computer system and steal your data. Like biological viruses, they are written to multiply and spread from computer to computer over the network. Viruses generally exploit a security vulnerability in the computer's operating system which allows them to spread and create as much damage as possible. Viruses can shut down entire networks and have been known to cost millions of dollars in lost productivity and lost data. You must protect yourself against these virus attacks by using antivirus software on your computer and by staying aware of any new virus activity.
