Buggy, buggy, buggy. Made too many critical systems crash in my experience. It used to be a great product until this year. Mostly the 2009 version is just awful and conflicts with too many programs, produces too many blue screens of death, and actually will halt some systems and force them to have to be rebuilt. Also had problems with their updates not catching enough of the viruses out there. From what I have seen on some very large network systems, it is now the worst product. Holy cow! OK, thanks for the info.
When I starting used Windows Server, I had to look for another anti-virus program, since Norton and McAfee (and others) didn't support Windows Server.
Around the same time, Ken Getz posted something on his blog about using Windows Server as a desktop OS, including good anti-virus programs. Trend Micro was recommended by Ken as well as others. Knock on wood, I haven't had any problems at all, and I'm using the 2009 version. (My browser takes about a second or two longer to load, but that's about it)
