After hours of running an illegally obtained copy of Norton, it told us where the file was and it couldn't delete it. Well duh freaking duh. <_<
So....the kid went to the dos prompt and removed it. Simple. Thanks, Chris!

I think the problem was that I never fully installed the virus.
But I shall be paying attention from now on and not be such a fat finger and actually DELETE my attachments intead of opening them.
Thanks everyone!!
