If mbam won't install or run
Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming
it. Right-click on the mbam-setup.exe file and change
extension to .bat
, or .scr
and then double-click on it to run.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change
as noted above. Then double-click on it to run.
Since you cannot use the Internet, manually download the definition updates
from another computer, save them to a flash (usb, pen, thumb, jump) drive or CD and transfer to the infected machine. Then just double-click on mbam-rules.exe
to install the update. If you cannot transfer or install from the infected machine, try installing the file directly from the flash drive to your machine.
Mbam-rules.exe is not
updated daily. Another way to get the most current database definitions is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref
) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system.

If you cannot see the folder, then you may have to Reconfigure Windows
to show it. Then perform a new Quick Scan
in normal mode and make sure you reboot afterwards. When done, click the Logs
tab and copy/paste the contents of the new report in your next reply.
