E-mail viruses: The message is the virus!

by Rich Pasco

Would you deliberately forward a virus to all your friends? "Of course not," you say? Well, many people do that when they unthinkingly follow the instructions in an important-sounding e-mail message that says "forward to everyone you know."

One definition of a virus is "That which tricks its host into making more copies of itself." This can be as true of an e-mail message as it can of a computer program or a biological virus. I call an e-mail message with this effect an e-mail virus. Fortunately, an e-mail virus is easy to spot:

  1. Says "forward to everyone you know" or "this is really true" or similar.
  2. Has urgent-sounding warning, a heart-wrenching plea, an offer of something for nothing, or a heart-warming story.
  3. Has technical-sounding language with details glossed over.
  4. Gives no reference to contact the original author for more information (phone number, e-mail address, etc.)
  5. Seeks credibility by naming known institutions, publications, etc., but lacks details (contact persons, publication dates, web pages).
  6. Uses terms like "yesterday" or "this week" in an un-dated message.
If you receive such a message and cannot verify its truth, please do not aid in its propagation, even if you trust the person who sent it to you. Remember, he too may have been duped. If you forward it because "it just might be true" you waste a lot of people's time and possibly embarrass yourself by demonstrating your gullibility.

Nevertheless, you should always practice "safe computing." Remember, to "open" any executable file (whether received as an e-mail attachment or otherwise) means to surrender complete control of your computer system to its distant (and unknown) author. Even if you know and trust the person who apparently sent it to you, please consider that his system may have been infected by a virus.
