Some types of malware 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.
- Alternatively, you can download a randomized renamed mbam.exe version (i.e. jdRjuT7Hk.exe) from here and use that.
- 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.
Another thing you can try, if you cannot run MBAM or complete a scan in normal mode, is to perform a Quick Scan
in "safe mode
Scanning with Malwarebytes Anti-Malware in safe or normal mode will work but removal functions are not as powerful in safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, MBAM loses some effectiveness
for detection & removal when used in safe mode because the program includes a special driver which does not work in safe mode. Further, scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. Additionally, there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible. For optimal removal, normal mode is recommended
so it does not limit the abilities of MBAM but sometimes there is no alternative but to do a safe mode scan. If that is the case, after completing a safe mode scan, reboot normally and try rescanning again.
