Currently I am evaluating NOD32 and Kaspersky AV for use on my 2008 Web Edition web servers. So far it is a pretty equal comparison with NOD32 being better at the following: -low memory footprint -fast scans AND Kaspersky better here: -better configuration defaults -nice default Microsoft exclusion/whitelist included (ESET really needs this...) IMO the kaspersky Windows enterprise version is even better, but the memory footprint on it is....monstrous, huge,crazy - basically unacceptable (can anyone say 300+MB idle?). Right now I'm leaning toward ESET NOD32. My main concern at this point is the plethora of threads about NOD32 v4.x being unstable and/or not recommended for servers (e.g. http://www.wilderssecurity.com/showthread.php?t=247327&highlight=windows 2008 ). Speed, configuration and detection are one thing, but crashing my critical servers is in a whole other ballpark. It is actually scaring the crap out of me In anyone's experience is NOD32 4.2.x proven to be "good to go" on servers - especially Win2008 SP2? Anyone running it on Windows 2008 web servers? Thanks to anyone who can offer their experience.
