A bit dated but still funny:
Coming to a hard drive near you, the worst computer viruses yet:
AT&T Virus: Every three minutes it tells you what great service you’re getting.
MCI Virus: Every three minutes it reminds you that you’re paying too much for the AT&T virus.
Paul Revere Virus: Warns of impending hard disk attack—once if by LAN, twice if by C:>.
Politically Correct Virus: Never calls itself a “virus.” Instead, it’s an “electronic microorganism.”
Government Spokesman Virus: Nothing works, but all your diagnostic software says everything is fine.
