Hello,

First I had the http://www.bleepingcomputer.com/virus-remo...system-defender virus, which those instructions involving Malwarebytes' Anti-Malware helped me get rid of, but now I have the http://www.bleepingcomputer.com/virus-remo...-antivirus-plus virus, and this time Malwarebytes' Anti-Malware is also disabled, apparently by the virus deleting the needed wbam.exe file from the Malwarebytes' Anti-Malware install directory. I even tried uninstalling Malwarebytes' Anti-Malware and reinstalling, but it never again creates the wbam.exe file, even after I reinstall in a different directory, such as Malwarebytes' Anti-Malware2 or 3. Even the Setup tells me:
"Unable to execute file:
C:\Program Files\Malwarebytes' Anti-Malware2\mbam.exe
CreateProcess failed; code 2.
The system cannot find the file specified.
The instructions for getting rid of this "Antivirus Plus" malware involve the use of Malwarebytes' Anti-Malware, so what should I do?

Thanks!

Hello,this should help.
-- Some types of malware will disable Malwarebytes Anti-Malware and other security tools to keep them from running properly. Others may delete the main mbam.exe executable file during installation or when attempting to perform a scan which results in various errors.

One way to resolve this is to download and install Malwarebytes Anti-Malware on a non-infected computer.
  • After installation, open Windows Explorer and navigate to the C:\Program Files\Malwarebytes' Anti-Malware\ folder where mbam.exe is located.
  • Copy the mbam.exe file to the Desktop and rename it to wuauclt.exe or explorer.exe.
  • Save the renamed file to a usb flash drive or CD, then transfer to the infected computer.
    • Another option is to upload the file somewhere so you can download it later to the infected computer.
    • If you do not have access to another computer, ask a friend to email or upload a renamed mbam.exe for you and provide a link to download it.

  • Place the renamed mbam.exe in the C:\Program Files\Malwarebytes' Anti-Malware folder on the infected computer, then double-click on it to launch the program.
  • Check for database definition updates through the program's interface.
  • Then perform a Quick Scan, check all items found for removal and reboot afterwards.
  • Failure to reboot will prevent MBAM from removing all the malware.
  • When done, click the Logs tab and copy/paste the contents of the report in your next reply.
