I use Malwarebytes which has malware and malicious website protection. Flags bad links (not that I ever click any) scans well. In all the time I have never had any threats from any anti virus I have used. Hopefully I never do but I don't go round dodgy websites or download crap so all will be good I'm sure. I might look for something to run beside it, if anyone uses malwarbytes with anything what do you use it with?
Eset Smart security works well along with malwarebytes, no conflicts at all.
Updates virus definitions all day long, even as soon as your computer is switched on, its saved my computer many times, good for backing up also.
