So, a short while back I got infected with Antimalware Doctor/Thinkpoint. We managed to manually remove them by deleting the files from another user account, but a lot of detritus remains. I have installed Malwarebytes, Super Anti-Spyware, Spybot Search and Destroy, Avast and AVG - because all of them keep finding different problems. (The computer already had McAfee.) In the end, I believe I have cleared out everything except one last problem...

Winlogon.exe and explorer.exe show as infected in AVG and Avast. AVG says they have the trojan Patched_c.JHH and .JHC; Avast says that it's Bamital (Bamital seems to be the more commonly used term, so I went with it.) Neither program can clean them, and no other program even detects the infection.

I should note that the only symptoms I'm having are occasional redirects with IE (I switched to Firefox and so far I have seen no redirects) and error boxes telling me I don't have permission to access files that spring up when I first open Firefox, pointing at files in my JRE6 folder. More precisely: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

This pops up twice, first with C:\Program Files\Java\jre6\lib\deploy\jqs\ff\..\..\..\..\bin\jqsnotify.exe in the title and then with C:\Documents and Settings\jclark\Application Data\Mozilla\Firefox\Profiles\9mbx003o.default\extensions\{E2283E8F-47...

I attempted to run ComboFix (yes I know I'm not supposed to, but I'm pretty sure it's the only thing that can actually stand a chance at repairing explorer.exe and winlogon.exe) but it would not work; I got multiple error boxes citing me not having permission to access files, similar to the above but with different files in the title.

Any thoughts? Thanks!

Hello,

Please follow the instructions in ==>This Guide<==. 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 and what you have done to resolve them.

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.

Thanks for getting back to me! I can create the logs no problem. I'll do so in a new topic.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic356955.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.

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