Bamital-AC; explorer.exe and wininit.exe infected, Malwarebytes not picking up

Recommended Posts

Yesterday, I managed to pick up a combo of Antimalware Doctor and the fake Microsoft Security Essentials virus. After a couple of go-rounds with MBAM and Spybot S&D, the above two seem to have been mostly nuked; however, I'm still experiencing some issues.

- To run MBAM at all, I had to rename the .exe, so something is blocking it from running.

- Running rkill.exe didn't turn up any malicious processes.

- Avast is preventing explorer.exe from launching, saying that it contains a virus; a scan with Avast reports that explorer.exe and C:\Windows\SysWOW64\wininit.exe are infected with the Win32/Bamital-AC trojan. (I can still run other processes via the task manager and cmd.exe, seemingly without issue.)

- However, running MBAM again turns up 0 infections detected.

Searching for "Bamital-AC" on the forums doesn't yield anything; a search for "Bamital" returns several threads, but none (so far as I can tell) for this incarnation of the virus, and all the instructions provided seemed pretty case-specific.

Any help you guys could provide would be much appreciated.

Sorry for disappearing, Borislav; after posting, I started having keyboard issues, and had to send the notebook for repairs. Murphy's Law, I guess?

Anyway, here are the logs:

Step 1

Please go into the Control Panel, Add/Remove and for now remove ALL versions of JAVA

Then run this tool to help cleanup any left over Java

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.

Please download JavaRa and unzip it to your desktop.

***Please close any instances of Internet Explorer (or other web browser) before continuing!***

  • Double-click on JavaRa.exe to start the program.
  • From the drop-down menu, choose English and click on Select.
  • JavaRa will open; click on Remove Older Versions to remove the older versions of Java installed on your computer.
  • Click Yes when prompted. When JavaRa is done, a notice will appear that a logfile has been produced. Click OK.
  • A logfile will pop up. Please save it to a convenient location and post it back when you reply
    Then look for the following Java folders and if found delete them.
    C:\Program Files\Java
    C:\Program Files\Common Files\Java
    C:\Documents and Settings\All Users\Application Data\Java
    C:\Documents and Settings\All Users\Application Data\Sun\Java

  • Check the boxes beside LOP Check and Purity Check.
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
