- An e-mail virus is computer code sent to you as an e-mail note attachment which, if activated, will cause some unexpected and usually harmful effect, such as destroying certain files on your hard disk and causing the attachment to be remailed to everyone in your address book. Although not the only kind of computer virus, e-mail viruses are the best known and undoubtedly cause the greatest loss of time and money overall. The best two defenses against e-mail viruses for the individual user are (1) a policy of never opening (for example, double-clicking on) an e-mail attachment unless you know who sent it and what the attachment contains, and (2) installing and using anti-virus software to scan any attachment before you open it. (However, some e-mail viruses may be so new when your receive them that your anti-virus software may not yet be familiar with it.) Business firewall servers also attempt, but not always successfully, to filter out e-mail that may carry a virus attachment.

The Melissa virus macro virus and the ILOVEYOU virus are among the best publicized of recent e-mail viruses. Each of these also spawned copycat variations with different words in the subject line.

Microsoft has been criticized for allowing its widely-used Outlook e-mail program to be so easily exploited by virus creators. Some users indicate that other e-mail programs such as Eudora offer the user more protection.
