(Apologies for long post)
1) Problem started with a virus with the following symptoms:
- persistent program failure message - some google program that had been disabled
- AVG anti-virus software is somehow disabled
- security center service is disabled
- occasional popups

2) uninstalled AVG and try to re-install, keeps failing (at a point where the service needs to be started)

3) tried downloading and running various tools - kept blocking, these, eventually, figured out that these can be installed and run ONLY BY RENAMING the exe - the malware seem to know the more popular names

4) Finally was able to rename install program install and rename exe and then run following:
a) Malwarebytes' ANti-Malware - this worked to remove 3-4 viruses, including some 'Root-kit' stuff

- I thought I was good to go but no such luck....I still see the iexplore task in the background (task manager) running like crazy going to sites and issuing search commands such as:
hxxp://www.locatewebsearch.com/search?q=pink%20lace&c=121336559&t=4224391737&m=0

This is one of about 5-6 websites that this background iexpore task keeps hitting, occassionally sound.

5) Since then have run IBM's Malicious Software removal Tool AND SuperAntiSpyware
- both have identified 1-2 viruses, quarantined all

6) Results
- All three programs now report NO malware
- Darn IEXPLORE STILL RUNS IN THE BACKGROUND
- UNABLE to permanently enable security center service
- UNABLE to install AVG or MS Security Essentials - looks like it is being blocked by Anti-Virus

Placing all the web sites in the blocked list in IE privacy tab does nothing... I had to block these by redirecting them in the hosts file.

I am at my wits end.... all these programs say no problem, but there obviously is a problem....next steps
Also tried running Win32kDiag - it fails with "Could not get backup privileges"

Some rootkits can terminate your security tools by changing the permissions on targeted programs so that they cannot run or complete scans. Further investigation is required to determine if this is the case with the issues you have described.

Please download Win32kDiag.exe by AD and save it to your desktop.

  • This tool will create a diagnostic report for me to review.
  • Double-click on Win32kDiag.exe to run and let it finish.
  • When it states Finished! Press any key to exit..., press any key on your keyboard to close the program.
  • A file called Win32kDiag.txt should be created on your Desktop.
  • Open that file in Notepad, then copy and paste the entire contents starting with Running from... to Finished!) in your next reply.
Then go to Posted Image > Run..., and copy and paste this command into the open box: cmd
press OK.
At the command prompt C:\>, copy and paste the following command and press Enter:
DIR /a/s %windir%\scecli.dll %windir%\netlogon.dll %windir%\eventlog.dll >Log.txt & START notepad Log.txt
A file called log.txt should be created on your Desktop and open in Notepad.
Copy and paste the contents of that file in your next reply.

I see there is a serious rootkit variant in this log. The rootkit itself is a protection module used to terminate a variety of security tools by changing the permissions on targeted programs so that they cannot run or complete scans. There are some new variants of rootkits in the wild right now that will require custom scripts to remove the infection, the process must be completed by HJT team members or above.

Failure to follow the proper removal process can and will cause serious damage to a machine. Recovery of the machine may be difficult, if not impossible.

Next please go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post the above Win32kDiag.exe log.

Let me know how that went.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/278750/rootkit-removal/ 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:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
