Having problems with Positive Finds

Hello,

I'm having problems with positive finds/gopropc/buzzdocads. They keep popping up in all browsers. I have:
-uninstalled all instancesof the above where I have found them and am now attempting to run the anti-rootkit from your instructions above but when I hit "scan" I get an error message that says "this version of mwark require you to exit the malwarebytes application completely."

I don't have anything else open or running as far as I can tell.

What do I do?

Zoek.exe v5.0.0.0...
