If it's not a suite, then augment it with a good firewall/hips that will cover a lot of possible malware intrusion points.

NB. You're probabloy better off with Comodo's free firewall and another antivirus, than using their suite, as unless it has improved a lot, the antivirus is one of the poorer ones
