I have deployed this to over 40 PC's on my domain. The deployment was very simple and easy. Also the fact that my users can't even see the agent is great, no more end user disabling. I haven't been running it long enough to know how effective it is, but so far it has cleaned up the messes that Symantec wouldn't. I wish that the remove infection was a bit clearer, but "delete from quarantine" is fine once you are sure it will delete the threat from the PC. I love the size and non memory over head of this, it is tiny and needs hardly any resources, unlike other AV solutions. Either way if this is as effective as the past product from GFI were, then this is hands down my Favorite corp AV, I have ever encountered. I have used Symantec (home & corp), clamwin, Kaspersky, Avast, AVG, etc etc etc... But with a 1minute install and management as simple as click click. There is really no better design out there.
