Hello bleepingcomputer folks:

Over a few years reading your forums has helped me, but now I request direct help.

Just like the post by sccomputerguys, one of our computers has the ZeroAccess Trojan. We started noticing problems in May such as browser redirects and shutting down of our security software. We thought we had fixed it when Microsoft Windows Malicious Software Removal Tool found about 8 items. However security software still reports existence of ZeroAccess Trojan, yet security software shows "Your computer is secure (no action required)". There seems to be a suspecious number of requests for Flashplayer and Java updates. Here is the information on the computer and what we have tried in the last few days so far.

-----------

System and software
Acer Aspire 5336
Intel Celeron CPU 900 2.2 GHz
RAM 3 GB
Windows 7 Home Premium, Version 6.1, Build 7601, Service Pack 1
Internet Explorer 9, Version 9.0.8112.16421, Update version 9.0.7 (KB2699988)

Security
McAfee All Access - Total Protection
Windows Firewall is Off

McAfee Scan Results
2 issues remaining
Unable to delete C:\Windows\Assembly\GAC_64\Desktop.ini (ZeroAccess Trojan)
Unable to delete C:\Windows\Assembly\GAC_32\Desktop.ini (ZeroAccess Trojan)

Other Scan Results
McAfee Stinger> Rootkit: clean Could not repair 2 Desktop.ini files above
Malwarebytes> found nothing
Kaspersky TDSS Killer> found nothing
Gmer.exe> found nothing
Windows Malicious Software Removal> found nothing
McAfee Rootkit Remover> found nothing

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

Your help will be appreciated.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic461751.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.

Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
