Computer Viruses

You can pick up a virus from an email or instant message attachment, free content you download from a website or on a disk someone shares with you. If your computer is not protected, once you download and install the program, the virus can spread.

When a virus infects your email or other files, it can:

• Make copies of itself, possibly filling up your disk drive.
• Send itself to everyone else on your email list.
• Reformat your disk drive and/or delete your files and programs.
• Install hidden programs, such as pirated software, that can be distributed and sold using your computer.
