Um, yeah. I deleted a virus off my computer and now it won't work.
Okay, some of those little boogers are nasty if you don't remove them the right way. Do you happen to remember which one it was?
Oh, yeah. See, like, I got this e-mail, and it told me "explorer.exe" was a virus, and like, Norton and McAfee wouldn't detect it, and I had to boot from a floppy and delete it from that black screen.
...if I sent you an e-mail that told you to strap five sticks of dynamite to your computer and light the fuse, would you do that too?
