List of computer viruses
Barack Obama virus: Conservatives say that this virus deletes all copies of GUN.EXE. Liberals say that this virus downloads a free antivirus. It actually does neither; it's just a normal virus with a darker icon.
Billy Mays virus: Permanently turns on Caps Lock.
Paul Revere virus: This revolutionary virus does not horse around. It warns you of impending hard disk attack -- once if by LAN, twice if by C.
Politically correct virus: Never calls itself a "virus," but instead refers to itself as an "electronic microorganism."
Oprah Winfrey virus: Your 200MB hard drive suddenly shrinks to 80MB, and then slowly expands back to 200MB.
Bell virus: Every three minutes it tells you what great service you are getting.
Rogers virus: Every three minutes it reminds you that you are overpaying for the Bell virus.
Ted Turner virus: Colorizes your monochrome monitor.
Terminator virus: Terminates and stays resident. It'll be back.
Pro-life.A virus: Won't allow you to delete a file, regardless of how old it is. If you attempt to erase a file, it requires you to first see a counselor about possible alternatives.

New World Order virus: Probably harmless, but it makes a lot of people really mad just thinking about it.

Ontario and Quebec viruses: Make sure they're bigger than any other files.

Elvis virus: Your computer gets fat, slow, and lazy and then self destructs, only to resurface at shopping malls and service stations across rural America.
Jimmy Hoffa virus: Nobody can find it.
Congressional virus: Runs every program on the hard drive simultaneously, but doesn't allow the user to accomplish anything.
Star Trek virus: Invades your system in places where no virus has gone before.
Wikia virus: When you try running Malwarebytes, it thinks it's vandalism and puts your system in read-only mode.
