Ok this is something about a virus that attacked my comp.

my comp was attacked by a virus from nowhere and now it has got into a real nuisance.
the thing is , whenever i try to open something related to the destruction or the removal of
that particular virus it stopes the program and freezes it!!!!

i cant believe that even symatec antivirus is not working against it!!!!!!

have some solution guys?????????
