Comodo Internet Security has just reached Version 3.9.xxxxxx
The Hips has certainly become a great deal more user friendly with whitelisting and trusted vendors(digitally signed stuff) plus buffer overflow protection.
Also the Anti-Virus has come on quite a lot with Heuristics and BOClean now integrated into it. Plus it`s free.

If you do give it a try, during install there is the option to install "Safesurf" for buffer overflow protection along with the "Ask" toolbar
just untick the three boxes (opt out) as it`s not needed now, BO protection is built into Defence+(the HIPS)
