Query: Not renewing, simply not worth the frustration.

I see I'm not alone in my frustration with this product. I bought ZASS after seeing that it scored highly in several 'reputable' publications and websites(which I'll now take with a hefty grain of salt from now on). Seemed like a good deal until I installed it. The constant warnings and alerts were annoying but expected. What wasn't expected is the way ZASS totally takes over my pc on startup. I have to wait anywhere from 1 minute to over 5 minutes for ZASS to finish loading up, initializing, scanning...whatever it is. Even after the initial startup I experience lock ups lasting a minute or so. A minute might sound like a minor annoyance but when you're on the internet or running a program having your pc lock up a half dozen times over a period of a couple of hours it becomes more than a 'minor' problem. For a supposed finished, non-beta product that you paid for it's inexcusable. No renewal from me.
