I smell a troll who's having fun at our expense.
The solution you want to wipe down your hard
drive can be had at any service station. It's called
gasoline--preferably, premium brand gas. It
interacts great with your hard drive's coating.
It will wipe out your pesky viruses in seconds.
To keep from seeing messages about viruses
on your monitor, I recommend that you swab
your monitor (glass or LCD) with acetone.
This way, you won't have to look at warning
messages: of course, you won't see anything,
either.
If you're going to shoot anything with a needle,
I'd suggest you shoot rubbing alcohol into
your friend's ass.
