Hi all. I am new to this forum but I am not new to computers. But I've got a problem I just can't seem to get licked. I seem to have picked up a trojan horse. It's called Win32:IWD. I run AVAST and it finds infected files (always in system32 folder), I have AVAST delete them, but the trojan horse keeps coming back. I have noticed lately as well that reboots seem to take a long time suddenly. I don't know if something's being done during bootup that I don't know about. At any rate, I have attached my HijackThis log so that hopefully someone will be able to help me get rid of this problem. I am very computer literate so I can follow any directions I am given.
