How are viruses, worm, etc. spread?
A common mechaniSMfor spreading a virus is e-mail. The virus is not in the e-mail message itself, but is in an attachment. The attachment may be a program or may be a document infected with a macro virus. Another common method is by obtaining a file (either a program or document) off a floppy or CD or by downloading from the Internet. Notice that some spyware and adware programs are downloaded when you download other programs that you want (and that you may be agreeing to this in the “fine print” of the End User License Agreement.) Some viruses spread without user help. They use system file transfer mechanisms or e-mail programs to replicate themselves. (Click here to return to top of page.
