I use CIS on on machine and avast with SRP (software restriction policy) on another. Avast cannot (in its present state) guard against 0-day stuff while CIS D+ can. On the other hand Comodo's anti-virus is to Avast a fist is to a gun.
But, CIS is improving like mad.. When BoClean added it'll be really good. CIS's D+ is a monster.
I think Avast should take it up a notch by introducing a Behavioural Blocker or Protection Guard for c:\windows* and/or startup registry keys (i put this in the wishlist too). This would make Avast directly comparable and competable. But as it stands CIS is awesome/the best, if a user knows what he's doing, whilst avast is awesome/the best, if they dont. I make my sis and girlfriends use avast... whilst i use cis myself.
Firewall.. etc. shouldnt be a priority IMO. thats just gimmicks.XP/Vista firewall is good enough and besides whatever firewall you make it'll leak in some form or another. why get bad publicity.
Get the Anti-Virus with Protection for 'Core' files/registry and you're through to the top.....
ps.damm i wish i owned a security company. id try to get it done myself. ....
ps.regardinng Comodo's revenue stream. it comes from certificate signing etc. if i remember correctly Thwate was sold to versign for $565million. .. so even if they're 1/100 ... i wouldnt' worry about comodo.... also see some vids of melih on youtube. that son of a gun is a sharp dresser (yeah yeah i know it dosnet mean anything... .. but still.. )
