I would not let this piece of garbage anywhere near one of my machines
if I could help it. Unfortunately there isn't much else around. The
things that I've seen with it are false positives, an inclination to
reset itself to factory defaults, an ability to bring a machine to a
crawl, and an inability to retain any settings. I also don't believe its
logs having compared them to a packet capture. I think it seems to just
make things up! Also it has the ability to cause machines to crash.
I worked in an organisation that encouraged users to use Zone Alarm. I'd
say that it was rare to go the whole week without ZA screwing up
someone's machine.
I used to use Sygate but that's been absorbed by the Symantec leviathan.
It's funny the way we grow to love/hate particular software packages,
isn't it?
Cheers,
Cliff
