I was watching an episode of Breaking Bad on videobb.com and broke my PC bad (pardon the pun). The Chrome window closed and it started popping up error messages. Everything disappeared out of the start menu and folders started disappearing. Most things wouldn't launch on double click but I did manage to establish a vnc connection with my other pc to capture a screenshot. Taskmgr would not open and basically the PC rebooted itself. When it came back up nothing was there.

I used cmd to navigate to program files and change it's attributes from hidden and then ran mbam.exe, it found one trojan.fakealert and removed it, and then I was able to shut it down and bring it back up in safemode. I ran mbam and it found nothing, I ran rkill and it found nothing, I tried to run gmer and it wont run, I tried to run DDS and it wouldn't run. I tried to run ASWMBR and it wouldn't run. Finally, I tried combofix and it got to 'Scanning for infected files...' which it stayed stuck on over night.

While I was at it, I unhid all folders. I am usually pretty good at identifying and removing malware, but since nothing will run but mbam, and mbam finds nothing, I am at a wall. I noticed many of the exe files in taskmanager were showing up as .3XE. I did get HJT to run, and it showed nothing (maybe 10 items) as opposed to the usual 40 or so line items. When I tried safe mode with networking, I could connect to the internet but it redirects me away from anything useful. HOSTS file does not appear to be altered.

Any thoughts on how I can begin to remove this without being able to run the most common tools to at least identify the malware? I was thinking of pulling the HD and swapping the registry files with the ones in system32/config/RegBack, but I am going to wait and see if anyone can think of something odd that the malware isn't accounting for that might give me an 'in'.

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.

DDS Runs until there are exactly 50 '#' symbols, then locks up. The mouse disappears, ctrl/alt/del doesn't work. Nothing can be done except hard restarting the PC by holding down the power button.

When trying to load up GMER I get an error: "LoadDriver("C:\Users\MEDIACENTER2\AppData\Local\Temp\pxldypoc.sys") error 0xC000010E: An instance of this service is already running.

Once the GMER window finally comes up, all check boxes except services, registry, files, and ADS are greyed out and cannot be selected. I went forward and pressed scan so it would at least go through the 4 that were checked and not greyed out and after about 20 minutes, I got the following error: "C:\Users\MEDIACENTER2\ntuser.dat: The process cannot access the file because it is being used by another process." Then it pops up GMER hasn't found any system modifications.

I don't know what to do. I am thinking that the malware has made some serious registry or permission changes that target the specific tools commonly used to repair PCs... :(

My apologies, I was unsure if I was allowed to post there without being able to complete the prerequisite scans. Thanks I will start a topic immediately.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic429124.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.
