Inspired by finding a list of Babylon 5 viruses earlier this week.
Harry Potter virus: Looks like the last file of a virus you just wiped out, until you try to erase it–then it wipes your drive.
Voldemort virus: You can’t get rid of it, only make it dormant. It can be reactivated by the Wormtail virus up to thirteen years later.
Dumbledore virus: Scares off all the other viruses but never seems to actually *do* anything.
Hermione virus: Fills up all available drive space with files of useless information.
Ron virus: Contains code, some of it buggy, from the author’s five previous viruses.
Draco Malfoy virus: Changes all your screensavers to insults.
Remus Lupin virus: Your computer becomes immune to all other virus and worm attacks, but three days out of the month it becomes a Commodore 64.
Weasley virus: Able to replicate even in limited space conditions.
Ginny virus: Looks like just another copy of the Weasley virus, but wreaks havoc every time you blog.
Tom Riddle virus: Masquerades as the Ginny virus, then retreats into memory.
Luna Lovegood virus: Repeatedly points your web browser to conspiracy-theory sites.
Slytherin virus: Your computer no longer reads hybrid CDs.
Gryffindor virus: All your games are reconfigured so you can no longer “Save As.”
Hufflepuff virus: Increases the efficiency of your computer, but gets no credit for it.
