You could consider to buy MBAM Pro. It’s a one time fee for a life time licence. What I like about them is that they have good relations with respectable malware removal experts/forums
What is your firewall (FW)? If you are using a strong 2-way FW with HIPS you should be fine with free MBAM. I use free (see my Signature). It all depends on your set up and how paranoid you feel…no pun intended.
And i think COMODO is more stable than Online Armor,BIG NOTE:You should be a computer expert to wrok with both so if you dont you just mess with your pc and lead it to a format.
HIPS stands for Host-based Intrusion-Prevention System. Practically it means that the firewall that has HIPS technology must learn which program you use; sometimes it will ask you if you want to allow a certain application that it doesn’t know of.
Both OA and comodo have HIPS (glad you like my humor ;D). Yes, HIPS does maximize your protection, so going with MBAM free would be fine.
I’ve done beta testing for FW’s to see how compatible they are with Avast. I don’t know if Superhacker has tested as well, but the new version of OA 4.5.1.431 is very stable in all OS’s. Comodo recently had a new release (5.x), so I cannot comment on the new version, however their previous version (4.x) did have problems for some who decided to go back to v.3.x.
