I have some virus (or something else) 
that no antivirus program can get rid of, i’ve tried mcafee (was installed when i got the virus), windows live one care, and norton internet sec. 2008. None can get rid of it, the computer will be sitting there, and an internet explorer window will open on its own to some random website, and once i turned on the pc and there was another user account i didnt create. So, does Dell PC restore format the hard drive [will it get rid of everything including the problem], or should i use the windows xp cd to reinstall the os. The pc is a dell dimension 2400.
