Oh ya, that's the MySQL virus. Unfortunately, you're going to have to take it in to get the harddrive degaussed. Or if you want to save some money, just find yourself the biggest magnet you can find, rare earth if possible, attach it to your harddrive inside the case, then power on the computer. That'll clean out the virus.
(disclaimer: I can't in good conscience leave this post without saying DO NOT DO THIS)
