CA doesn't produce software. They aren't a developer. They buy someone
else's software or rebundle it and put their name on it. Their firewall
in their EzArmor bundle is a rebranded and older version of ZoneAlarm.
I don't know from where they get their anti-virus engine but do remember
that they acquired it from somewhere else. I cannot remember ever
seeing it listed at av-comparative.com but then that site may be rating
the source AV engine rather than the rebranded version of it.
They have 2 scanners in their package. One was the Inoculate-IT one, the
other was the Vet one. They suggest picking one for servers and one for
workstations, but via the management console you can assign either to
any machine or group of machines.
Before CA bought it, we used to use Vet here and it was pretty good back
then. I can't speak for what it's like now.
