Hi,
Here are couple troubleshooting steps you can do to completely remove a software.
- Start by deleting all folder related to Malwarebytes.
- Go to C drive then Program Files and delete Malwarebytes folder.
- Press the Windows key + R at the same time and type in %appdata% then press Enter. Once the Roaming folder is open find and delete any Malwarebytes folder.
- Press the Windows key + R again then type %temp% then delete everything in that window but if it won't delete just leave it.
- Press then Windows key + R again then type prefetch and do the same, delete everything.
- Now open Task Manager and disable all startup items specially anything related to malwarebytes.
- Reboot your PC then check weather there will be any traces...
