I got a serious problem with a virus i got, seems that it is infecting the csrss.exe file of my OS (windows 7 64bit). My antivirus MSE (Microsoft security essentials) gets to block the program and also the Malwarebytes does blocks it, but the thing is that they never get to find the infected file and delete it 'cause the treat disappears. i got only 3 csrss.exe files on my pc, on system32, system64 and a folder named AMD which i checked and is legitimate. I have run the scaner on safe mode, without being connected to the internet, i tried the Regedit thing and the values are ok, i tried the CCleaner, i have tried everything and i still have the virus on my pc, and i have had to restore the pc to a previous date 3 times already cause although the virus is being blocked it is damaging my system somehow. BTW the task manager only have 1 csrss.exe running. I'll appreciate a LOT any response, thanks ahead.
