Hallo Oldman,

I have performed the suggested procedure, but the trojan is still there.

My experience is similar to that of dholyday i.e.

  • SuperAntiSpyware does not find the Trojan
  • Avast does find the Trojan
  • Upon Boot scan with Avast with Archive ON Trojan file is found but remains Access Denied

I also tried (unsuccesfully) a low-tech solution by copying a non-infected copy of c:\windows\system32\ac3ap.dll[UPX] from partition e: and replacing the infected file.

  • have you any idea of what this trojan exactly does? If it simply “spyes” on me there will be no problem: I never process sensible/confidential information on this PC/connection.

  • it must be connected to Internet explorer because when I start the browser avast pops up with it. So what will happen if I simply stop to use IE and use anoter browser instead? (Opera? what is the most basic one?)
