Usability complaint Thursday, not particularly veiled sarcasm edition

I've got an idea for an awesome computer virus. Here's what it will do. At irregular intervals (think weeks or months) it will cause a dialog box to appear reading something like:

Automatic Updates
Updating your computer is almost complete. Your computer needs to be restarted for the updates to take effect. Windows will restart your computer automatically in five minutes.

Do you want to restart your computer now?

Naturally, restarting will be the default option, and the dialog box will float on top of all other processes until you deal with it. Also, if you dismiss without restarting, the dialog box will reappear ten minutes later.

Man, that would be annoying. If only I could get somebody to write it...
