Well, thanks, i have tried safe mode scan, and my system is clean, and altough is sayin the memory scan that is infected, again with win32:AutoRun-AKO. I have tried Avast PRO Full Scan, Malwarebytes Full Scan, SAS PRO Full Scan, Outpost 2009 Pro Full Scan, also an Avast Bart CD 2.0 Trough Scan, and nothing. All scans says, no infection found.
Thanks for your help.
I'll wait for a SAS Update, so i can see if it corrects the problem.
I attached my hijack this log. Hope it can help.
