Hi, Guest
I'll restrain myself this morning and say that "big AV" companies exist for a reason - because you'd be hard-pressed to trust free AV when you're responsible for an entire network of servers and users. Free AV companies tend to take the "oh well" route when something they do breaks something of yours. Tech support tends to be less-than-stellar too.
We run McAfee here (have for over 5 years) and I watch our detection reports very carefully. GroupShield for Exchange has to be one of the best on-transport scanners I've ever seen/used/read about. VirusScan 8.5i has a great suite for protection.
Hell, we ran into a scenario where by default McAfee Enterprise 8.0i/8.5i stopped our email archiving software from replaying a message because we hadn't made a policy "allow" for an IIS process. That is what keeps you from being much closer to a bot-infected open relay (or an ever-present IIS overflow/hole exploited-bot), something that can be potentially quite damaging to a company's reputation and revenue flow.
