"Very good AV"
Heuristic engine(System Monitor)very good!
Good System scan (full scan 40 min.)
Memory used: moderate. Can be heavy on older PCs
Separate rootkit scanner.
Struggles with 0-3 day old malware
Has a simple GUI. This AV can keep your system up-to-date with vulnerability options. As far as keeping the system clean, it struggles to keep adware bundle junk out for the most part. Has a separate scanner for rootkits. I'm not sure if the Full scan option scans for rootkits or not. Would be silly if it didn't. System Monitor,their heuristic engine, works great! It caught viruses that the definitions missed.
For a paid AV, IMO, I've seen better. K7 ,however, is a step on the right direction.
