My avast! informed me it found a trojan horse. Whatever I do, virus stays where it is. I can only click ‘no action’.
Virus is in WINDOWS so I dare not to delete it manually. What should I do?
virus name: Win32:BHO-KD
virus type: Trojan horse
infected file: cdosy.dll (which is in folder ‘system32’)
Please help me by answering! Thanks for answers in advance.
