Oh powers of rootkit removal, help me!

A probably MSN-related infection has struck me, and I'm out of options on what to do. AVG Free grabbed my attention with "Threat was blocked! - filename: security-pc2011.biz/?code=1373 Threat name: Exploit Rogue scanner (type 922)" while browsing the net with Opera 10.10 (Vista Home Premium). Now both Opera and Firefox (to which I switched when this started) display random casino/IQ-test/whatnot popups. I've done the following:

- Ran full sweep with AVG (nothing found)
- Scanned the comp with Malwarebytes Anti-Malware (nothing found)
- Scanned with SuperAntiSpyware Free (nothing found)
- Scanned with Spybot S&D (nothing found)
- (following instructions), ran ComboFix, but it didn't resolve the issue. Popups came back.

All the definition files, Windows, progs were up-to-date.

Like you haven't heard this before: HELP ME! Please!

Forgot to add that there's no actual search redirects or anything like that, just that the browser displays random sites in a new tab occasionally. I know this about viruses/trojans etc., but can a rootkit infect flash drives and other computers by hiding in emails or something like that?

How do you know you have a rootkit?

It wasn't detected by any of the regular malware/virus scanners and the symptons are much like some of the other infections on this site identified as rootkits. But I'm just guessing, any help is much appreciated!

Update: eSagelab rootkit removal found rootkit.win32.tdss.y in atapi.sys file. It wasn't able to remove it though, as it crept back after the reboot. Any ideas?

Update #2: Kaspersky's TDSSkiller identified and cured the files. So far so good, no popups! (fingers crossed). I'll continue to observe the situation a few days and then reply here if it's ok to close the thread. Still a bit paranoid, but let's hope it's gone for good.

Hello elukka,

That is a very bad rootkit, and TDSSkiller has been known to cause problems and also may not complete the job. At this point, I advise following the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<==

If you cannot produce the DDS logs, then post back here and we will provide you with further instructions.

Hello elukka,

I see that you have your logs posted. Now for the hard and frustrating part: waiting.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/290375/rootkitwin32tdssy-infected-atapisys/ 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 HJT 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 HJT 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 HJT 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 HJT 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 HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks perhaps less, 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.

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

Orange Blossom :thumbsup:
