MalwareBytes: Context menu lost

December 28, 2017

This post is for me in case this ever happens again. If it helps you too, great. But if it doesn’t work for you, don’t ask me for help as I don’t have any knowledge of the MalwareBytes AntiMalware (MBAM) program — instead, contact MalwareBytes directly (https://www.malwarebytes.com/).

What happened

MalwareBytes notified my husband of an upgrade (to v3.3.1) and he did the right thing and downloaded and installed it. But he lost the right-click menu option to ‘Scan with MalwareBytes’ in Windows Explorer. We reset the MBAM setting for the context menu, rebooted the machine, downloaded and installed any upgrades (there were none), and gave up in despair as it was Christmas and my IT people were on leave and only available for emergencies. This wasn’t an emergency — just an inconvenience to have to manually scan a folder via the main MBAM interface.

Today, my IT people were back on deck so it was time to get it sorted out.

After checking user forums etc. my IT guy got back to me and checked the Registry settings. Nothing seemed untoward. Then he uninstalled MBAM (there’s a specific process he did for this, including using the proper MBAM clean-up tool, stopping MBAM and other services such as SuperAntiSpyware and Webroot, rebooting the machine, reinstalling a new copy of MBAM from their website, rebooting, enabling the other services etc. — I left him to it!).

But the end result was the same — still no right-click option to ‘Scan with MalwareBytes’ in the context menu.

Then he had a brainwave — I had told him earlier this afternoon that my MBAM upgrade to v3.3.1 went through successfully a couple of days ago AND that I had the right-click scan option. Both were Windows 7 machines.

Solution

He checked the Registry on my PC and found a setting for the context menu for MBAM, which wasn’t on my husband’s PC and which wasn’t where he’d expected to find it. He saved that setting, copied it to my husband’s PC, then merged it into my husband’s Registry. After a reboot, we had the context menu back!

For anyone else who has this issue, check for this Registry entry:

  • HKEY_CLASSES_ROOT\AllFilesystemObjects\shellex\ContextMenuHandlers\MBAMShlExt

If it’s missing, you’ll probably need to contact MBAM to get the details for it.
