I have had a problem for a couple weeks now that my Antivirus software (ESET NODE32 Antivirus 4) has been detected but unable to clean the Win32/Olmarik.ZC trojan from the Windows NDIS file when I run a scan. I then more recently got a Fake Attacked by "Antivirus Suite 2010" and purchased & installed Malwarebytes to help me get rid of it. I was able to do this but in the last few days ESET NODE32 is now reporting Win32/Bamital.EQ trojan the moment I power on the computer. It reports this Threat in the object C:\Windows\system32\wininit.exe during an attempt to access this file. It gives me the option to Delete or take No Action but when I choose Delete it reports "Error while deleting" and a new Threat is reported by ESET NODE32. The new Threat is the sam Win32/Bamital.EQ trojan but the object has changed to C:\Windows\explorer.exe. If I choose to Delete this it again reports "Error while deleting" and a new Threat is reported by ESET - again its the same trojan but its back to the prior C:\Windows\system32\wininit.exe object. Each time I choose to delete the same threat ping-pongs between these two files.

My PC is running Windows Vista and as I mentioned I use ESET NODE32 Antivirus 4. I've tried running this and Malwarebytes in Safe mode but the only thing that is found is Win32/Olmarik.ZC trojan in the Windows NDIS file and ESET is unable to clean it. i.e. no Bamital.EQ trojan is detected.

One other note is that when I'm connected to the internet Malwarebytes is reporting that it is blocking access from 2 IP addresses on a continuous basis (numerous times a second according to its log). Every now and then (mostly when I try to print or start the Window Task Manager) Malwarebytes will report C:\USER\BILL\APPDATA\ROAMING\BITRIX_SECURITY\YALPIRAI8.DLL Trojan FakeAlert but it Quarantine fails when I select that option. I can not open Windows Explorer any more - Windows reports that "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item". Similarly is will sometimes report C:\USER\BILL\APPDATA\ROAMING\ANTIVIRUS_STUDIO_2010.EXE Rouge.Antivirus2010 Quarantine fails when I select that option.

So, bottom line, I appear to have a lot of problems and don't know where to go from here. I've completed the recommended bleepingcomputer preparation steps and look forward to getting some expert help.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic359212.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.
