After Qihoo 360 TS, Norton Security, Tencent PC Manager, F-Secure SAFE, Quick Heal Antivirus Pro, Internet Security and Total Security, I found K7 serving my needs best (light, unobstrusive, built-in firewall, signatures are updated hourly under the week, weekend after some hours, in-app-upgrades of the software without the need for user action, sometimes a reboot).
It might not have the potent Behaviour Blocker Quick Heal has, but they both ramp up signatures and Behaviour Blocker recently (i remember v15 way weaker than the current v16), it comes with an customizable firewall (even if I'd wish it wouldn't autotrust Windows services), and is light as a feather on my two machines.
Only had a quick glance on Bitdefender and Kaspersky long time ago, and more recently Vipre, which was heavy.
