Hey everyone, well, straight to the point. Im having problems with a darn trojan that just wont set loose and leave me alone. Its called Hacktool.rootkit, supposedly kinda new, Im not sure. It affected my ntoskrnl.exe and just wont go. My antivirus supposedly deleted it, but it keeps showing up again and again and then keeps saying it was deleted. Its a system file so I cant just get rid of it. I've tried everything, NoAdware, Ad-Aware SE, Spybot, AVG Anti-Spyware even AVG Anti-Rootkit and it didnt even find it. I have no idea what to do next, Im downloading NOD32 but I doubt it'll work. I'd really appreciate any other solution rather than just formatting! Thanks in advance! I forgot to say, the symptoms are, besides the pc being INCREDIBLY slow, the mouse stops working for several minutes, like, it would move but it wouldnt do a thing, so happens with the keyboard and all of a sudden it would work again, but sometimes id have to restart. On msn I keep sending nudges and some weird file i did not place on my pc keeps being sent to my friends when im chatting... i would really love it if someone could help! i dont wanna have to format again! thanks once again!
