currently still have trend micro internet security (free license from my dads company). Since its free for me i dont have high expectations, but its a pretty complete package. As far as internet reviews go its no the best in detection and removal of virusses, but the completeness of the package is probably the best there is. Luckily i have a brain of my own, and are behind a hardware firewall, so i dont have to rely on this alone.
so far, the things ive discovered are: virus (duh), firewall, network security (it also detects if new wireless clients are added and such), scans email + attachments (works for thunderbird as well

), phising (sp?) detection, blocks suspected websites and programs, detects suspicious program behaviour, etc.
