On the 20th of this month, my computer was hit with a large group of viruses... TDSS, root.kit, and others. It stopped access to the internet, and looks to have damaged/removed some windows files.

I ran Spybot S&D, Malwarebytes, TDSS killer, Bitdefender (my current anti-virus), and finally combofix at the request of a professional that I had phoned. It seemed all viruses had been removed, but it took deleting anti-virus and installing again to access the internet, and some things are still unstable/don't work. After all of that, one of the viruses has also tried to come back twice more (Trojan.Sirefef.HT, sys32\services.exe.vir) so is obviously still imbeded somewhere on the system.

Current issues still at play:
-Bit defender has a critical error/crash every 20 minutes since being installed, and wants to be restarted all of the time. It seems it continues to function even after the error, but I don't know at what capacity.
-Windows Update no longer functions. I either get an 80246008 or 80246016(?) error. Have tried online solutions for repair to no avail.
-SFC /scannow says there are corrupted files, but when I try to use the findstr command it gives an error, so I can only look through the huge log, aka I am lost on that one. ((EDIT: Got sfc to drop the txt file to the desktop, so I have that log to look through now))
-Cannot use system restore. The virus destroyed all system restore points, up to a system restore created by combofix on the 24th. Even trying to access system restore from another user in safe mode, or from boot no longer shows any other restore points. Even that restore point is no longer accessible because when I tried to restore to it, or at the time a point from the 20th (no longer there) I would receive an error that the file C 1147.NLS was missing, and would abort the restore.
-I'm pretty sure there are a few more sys errors and such that I am just not remembering atm. Will update any more if/when someone responds :)

Tried creating a new user and switching over to avoid some errors, but none were fixed.

Thanks for the help!

Now that you have posted your logs here http://www.bleepingcomputer.com/forums/topic462719.html/

Please refrain from asking for further help from other members or staff until the Malware Removal Team has checked your posted logs. The Malware Removal Team work very hard to investigate a unique solution to your problem and you will receive individual expert assistance. This takes time and effort so we ask you to please be patient while waiting for assistance and NOT to make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member. Any modifications you make on your own can result in system changes which may not show it the log you already posted. Further, following advice outside of that post may cause confusion for the team member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

The Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean. If you followed any other advice already, please ensure you inform the Malware Removal Team Team Helper when they respond to assist you with your log. This will help them know what has been done and they probably will ask for an updated log.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Removal Team member is already assisting you and not open the thread to respond.

If HelpBot replies to your topic, please follow Step One so it will report your topic to the team members.

This topic is now closed.
