help norton on my pc detected some trojan mourner and i have searched many sites even google and antivirus respective sites but these site don't even know there is anything like this how to fix that?
Try online scanners...
Mrintech used to post some links...let him comment.
Download avast antivirus and run a boot time scan. Also, could you post the name of the trojan?
Mrintech knows some good online scan sites, but he's offline right now. Meanwhile, try Trojan Remover :*www.simplysup2.com/download/dl/trjsetup675.exe
