At least i believe so. Since rebooting due to a stop 8e around 2pm yesterday, upon restarting and opening Firefox it automatically opened a new tab listing a generic "site visitor blah random prize notification" page. At that moment Avira started warning about a Bobqblr.sys in system32 which i clicked to deny access at once, however Firefox is completely hijacked depending on some sites such as Wikipedia, antivirus, antimalware, but interestingly MSN is not redirected to some random site that at least noscript is blocking. Except of course for the winner splash page and a Osu or something questionnaire.
Running spybot proved to find nothing, however avira was throwing warnings now about a idzd90peso.dll and cx5jp.dll, but by the time spybot finished this was followed by uhjb.exe, mmpmegx.exe, and a ofgitsly.exe. Since spybot failed to find anything i tried malwarebytes, and it quickly found six files which it removed. After rebooting, and re-unplugging the cable modem i ran a virus scan, and it found six randomly renamed .htm files in system restore which i then followed with another full scan of malwarebtyes only to find 1 sys and 5 .exes in another part of C:'s system restore. I have since disabled restore via system properties.
Currently Firefox is still randomly opening either the questionnaire or the winner splash page depending on the site visited, but still causing random re-directions on tech help sites/anti-virus and the like. However Windows update seems to not have been disabled at all, my wallpaper wasn't replaced, anti-virus wasn't disabled, but Safe mode is completely unable to be accessed always now causing a Stop 7e at GiveIos.sys. In addition there is still a mention of a Bobqblr.sys in non-plug and play devices that is set to stopped.

Trying to find information about the virus files themselves so far seems to be quite difficult due to Avira not even having the names it lists in its own database while Malwarebtyes gives two different listings for each file, one in the main menu with a different one in the log file. Then trying to upload the now quarnteined .sys file (700kb+) to totalvirus resulted in only 3 replies (Drweb, F-Secure, and bit-defender) which left me more confused.
Basically
Bobqblr.sys
Avira: TR/Rootkit.Gen.
Malwarebytes: Rookit.agent
F-Secure: Generic Rookit
DrWeb: Backdoor.trojan

However for the first of the six htm files listed in system restore, malwarebtyes lists the largest as TDSS.Rookit, while the other six files that still have extensions in restore like .sys is still listed as rookit.agent. Basically for malwarebytes they are Trojan downloaders, and one Fakealert. Avira while agreeing that one is a TR/Fakealert.inj, lists the rest as two Ertfor B.15, one as a Ertfor A.33, and the fourth as TR/Crypt.Xpack.Gen.
Seriously does the industry not understand how completely confusing this is, or worse in avira's case listing viruses (Ertfor) that do not have actual discriptions in their database? sigh.
So basically from what i can see i
A: Have a Rouge anti-virus that failed halfway to install or B: The TDSS Rookit which either succeeded in infecting the system for the rouge, or also completely failed halfway through. C: All of the above or no clue at all what actually is going on.

While i am able to create a DDS log, GMER seems to cause explorer to freeze along with everything else after a minute or so. I did uncheck those 2 boxes suggested by the faq page

Don't worry about the GMER log. Go ahead and post the DDS logs in the new topic and explain what happens when you try to run GMER.

Note that you will be posting in this forum: http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

not this one.

Hello,

Ah, good.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/298855/possible-rookit-with-hijacked-browser/ 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.

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

Orange Blossom :thumbsup:
