My Mac is up to date with High Sierra and Firefox Quantum.
Since the installation of Quantum I've had a flurry of problems. For some of those, I was advised to download MWB in case some had resulted from malware. I know exactly how rare those are on a Mac anyway, but was told it wouldn't hurt.
The recommendation specifically mentioned adwcleaner, which I can't find for Mac - only an .exe file for Windows. So I opted fro MWB for Mac.
I've installed it twice now, and - there's no MWB. That's to say, I complete all the installation steps, and I get the confirmation that it's been installed. I look for MWB anywhere on the computer, and it's just not there. Spotlight can't find it; I've done manual searches; nothing. It doesn't exist. All that's left is the installer package.
I did download MWB free once in the past, but that's nowhere to be found either. And I'm not getting any messages that - for example - I can only download it once.
Where might MWB be lurking, and if it's truly not on the machine - what's happening with the false installation?
Is adwcleaner part of the total Mac MWB package?
If I do successfully install this, will it kill the floating/sticky video windows that follow me down the page on news sites? That was the original question that led to the advice (and you can see why I doubted this was the solution).
Thanks for any help you can offer.
