Here's the deal. Yesterday, at around 2:30am (meaning it was basically today,haha)I was on a video-streaming website watching TV shows, and I foolishly allowed the outdated Java script to run. After this, MSE, Windows Firewall, and Windows Update became disabled and i got error 0x80070424 when I tried to enable it. Scans with various programs showed that I had a decent amount of trojans. Then I decided to perform a system restore, and restored my PC to a restore point 2 days ago (july 18th). at this point, everything was working correcty, so i performed a scan with MSE and found the dreaded sirefef trojan. I deleted it, and to my surprise MSE actually said that it worked...and further scans showed up clean. I then did a scan with MBAM, and found a few trojans and adware programs that I promptly deleted..again it worked. i ran more and more scans throughout the day...and nothing was showing up - HOWEVER, during a full scan of MSE, my computer randomly restarted for no apparent reason...this has not happened since.

I've run scans with MBAM, MSE, HitmanPro, TDSSKiller, Norton Power Eraser, ESET Online Scanner (which found and removed a trojan and an adware program), EZ_Sirefix, ESESirefefRemover, SuperAntiSpyware, and ComboFix (I know I shouldn't have, but I did anyways - stupid, I know)
... and all of them have come up negative, other than the ESET Online scanner which i mentioned.

My question is: is it safe to say that my computer is free of this Sirefef/ZeroAccess malware, or should I simply do a nuke and pave (as I am aware that once the system is compromised with something like this, it really can't be trusted)?

also, if i were to do a nuke and pave, would it be safe for me to back up my documents? because the only thing that is important on my "infected" computer is some school documents..everything else is unimportant. will simple word documents and powerpoint files be infected as well?

thanks!

and just to add, i am running windows 7 x64

Since you have run combofix without supervision :nono: ...

------------------------

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

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

Regards, dev00790

Thanks for the quick reply, but in terms of formatting the drive and re installing windows - would that get rid of a potential infection 100%?

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic461689.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY 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 make another reply until it has been responded to by a member of the MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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

To avoid confusion, I am closing this topic. Good luck with your log.
