I so know what you mean
I just got fed up with NAV screwing up Word, freezing my system every time it does an auto update, and paying the big bucks.
I was gonna go with the PC Cillin Suite, then I got to reading about how sometimes it's better to go separately, the ideaa being a company does one
thing very good, not quite so good the other things. Personal preference, and I may change my mind.
So, I'll be using ZA Pro (cuz I like the idea of having a CD to install) and Avast!, or BitDefender.
I run WinPatrol and update weekly.
I also scan AdAware, SpyBot and SpywareBlaster once a week, after updating if necessary.
Another thing, many of the the firewalls and AV systems out there often have user forums, which are life savers.
Norton support ls like MS support: just too big and impersonal. Although, they did help me when their product failed.
