This product is not compatible with ZoneAlarm Security Suite. I was running that but on a slower PC ZA's virus scans are too slow.

So Avast installs fine, scans fine on the first bootup after install, THEN tells you that it's not comp. with some feature in ZA and that you should turn off the incompatibility in Avast, THEN you need to go and set up special proxies in your browser(s) to make web pages load correctly.

Screw all that, too much of a problem, and REALLY REALLY irritating that the program didn't tell me RIGHT UP FRONT that it wasn't gonna be compatible with ZA instead of letting me get it all installed and spend 10 minutes running a startup scan...how utterly STUPID is that? Then you have to go through the hassle of uninstalling it if you don't want to have the hassle of setting up your web browsers special...which I don't, why bother? ZA will scan at night when I'm not at the PC is all. I *did* like Avast when I tried it on another computer I thought it was fairly quick...but this mumbo jumbo letting me install then getting all this crap...well bye bye, try again Avast authors. And another thing...if it's not compatible with ZA, then who knows what else it won't be compatible with...guess you take your chances if you're running something else, cuz they sure won't tell you up front!
