Hi acidkillz2001.
Sorry for being so abrupt before. As scythe944 says you still have options that you can add to make your defense plan even more effective. With avast resident and MBAM you have good bottom-line, and from what I gather COMODO is very good firewall (with avast - as stand-alone unit set apart from comodo AV suite). I've never used comodo firewall so I cannot comment further on it, others here have so some info will be available in the forum.
You can work well off your bottom-line and strengthen your defense layers, "hosts" file protection is certainly a good strategy, but two AV resident is not good defense policy.
All good advice forthcoming from avast forum contributors like scythe944, so clever move coming here. My experience is that it just keeps getting better.
Regards
