I have used Webroot Secure Anywhere for several years- indeed that was a result of being badly let down by Macfee as were hundreds in my home area at the time. Webroot is, in my opinion, lightning fast at warning of a ‘phishing’ site or other dangerous location, not that much gets past WSA. The ‘techie’ support has been excellent and quick- and better still free to WSA subscribers.  I use Malwarebytes (Free Version) as a backup for an additional scan system, as needed. This AV system is pretty good at spotting PUP’s amongst other things, but as I say WSA which runs ‘in the cloud’ in real time does spot most things- even a ‘nasty’ in C Cleaner. BTW I uninstalled C Cleaner.  As above just my experience & opinions.
