lately my computer is infected by... maybe some trojan viruses, some of them still unindentified whether it is trojan or spyware, when I press Ctrl+alt+del in my processes tab, I saw some exe file that are not supposely to exsist, I use AVG, antivir, Norton but the antivirus doesn't able to detect them as viruses, I use spybot but also no luck... so is there any software that can solve the problem above??
