Personally i like malwarebytes, just dont ever use macfee or norton, those are SHIT. Trying to remove them is like trying to removing a virius itself, such crap.
Macfee and Norton tried both of them, not very good Norton firewall was ok and easy to use, but getting them off the computer was horrendous, esp Norton had to use Norton Removal Tool after the normal uninstall. It left lots of unwanted registry stuff lots of it.
Eset Smart is my main choice now, had it now for more than five years.
Edit to add I use Malwarebytes also.
