Threat Win32:sirefef_Pl [Rtk]

[Wrrrtw]

Hello.

At the beginning of the month, I received one of those fake antiviruses viruses, and I had since believed I deleted it.  Using avast, Mbam, and a CCleaner, I had removed what i thought was the source, and thus 'got rid of it.'

I scanned daily for about a week to ensure there was nothing to pop back up, and all seemed fine save for a few issues involving flash, and the Opera broswer.  I have sense moved browsers, and thought my problems were solved until this afternoon when my computer started alerting me multiple times (and continues to do so) that a threat has been blocked.

After scanning the infected folder that said threats were in, I have found the following viruses.

Win32:Sirefef-pl [Rtk] within C:\windows\assembly\Gac_32\destop.ini and within ...\Gac_64\desktop.ini

I have been alerted by a friend that is is a potentially severe issue, and that i should consult this forum.

Here are the OTL files for starters.  I will post/edit with the Mbam log here soon, once Mbam's scan is complete.

Edit: OTL Extras

Double post

Here's the AswMBR.txt

EDIT
And i've added the Mbam log.

Due to fear of the severity of the Rootkit and the Trojan downloader, Along with no mods/admins/support on at the time of this post... I have deleted both rootkits in avast, and deleted the trojan downloader in Mbam.  The infected machine is running avast's boot scans.  I am hoping that this is the end of Sirefef-pl, but i've been wrong before.  any assistance involving removing unpacked files, or anything involving any rejuvenation of the deleted files would be appricated.

I have decided to format my machine to fully root out the issue, based on the warning that Jeffce has had with the users that have similar issues. 

I do not fault avast or the message board's user-base for a lack of reply, actually I appreciate all the information already logged here.  Keep up the good work.
