I have exactly the same problem as mentioned on http://www.techspot.com/community/topics/sirefef-ai-and-ae-and-patched-b-gen-trojans.182121/, I don't know whether it was a coincidence but infection happened during installation or download of an adobe flash player update. When Eset began to popup virus alerts I cancelled the adobe update process , cause I thought the update might be a fraud. Now , Sirefef.AI and Sirefef.AE keep popping up with ESET Nod; Patched.B.Gen Trojan keeps being alerted to me by ESET and it fails to delete the trojan. ESET spots C:\Windows\System32\services.exe as threatening object for patched.b.gen. I am running a Windows 7 64bit , .. Since on the forum page mentioned above (http://www.techspot.com/community/topics/sirefef-ai-and-ae-and-patched-b-gen-trojans.182121/ ) there was a warning as "This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system" I hesitate to clear it myself and requesting help. The removal process on that case was pretty long and sophisticated, I was wondering whether a shortcut is available. Thanks in advance.
