I'll probably get flamed for this - but what NOD32 is missing that SmartSuite has is what you don't want anyway - the personal firewall.
If you don't have a good perimeter firewall, get one. But personal firewalls - if they are controlled to the point of actually being useful - are very intrusive and cause far more issues than they ever fix. And because of the Windows architecture, half of what you'd want to ideally control for is lumped under "system" and even worse, "svchost" - and you can't control for it separately anyway. Conventional wisdom argues that you "need" a personal firewall, but on an effort/reward ratio scale it's one of the least useful tools you can use.
All IMO, YMMV of course.
