I have been using CryptoPrevent
https://www.foolishit.com/cryptoprevent-malware-prevention/?ModPagespeed=noscript......but I'm watching MB Anti-Ransome as it progresses....not a fan of "beta" software.
I use MBAM now with Avast and also run MBAE.....all play well and do not bog down PCs.
I'm hoping MBAM integrates MBAE & MB Anti-Ransome at some point (they stated they would) but I do like they have these separate and light.
Thus, you can keep your baseline protection that is solid why you decide/eval new "layers" of protection software.
Frankly, I wish Avast would do the same thing instead of borking down a great A/V with bloatware that forces users to basically opt-out and not try.
I like MalwareBytes marketing scheme MUCH better than Avast...who seems to be more like the Symantec philosophy/angle of "push-ware".
Oh yeah, Avast CEO & Chief Strategy Officer came from Symantec.
