Hello it´s real that PC Tools AntiVirus Free Edition v4.0 works fine in Windows Server 2008 but it have some issues, for examples some times (not always) when it try to check for updates the system show an error message which continues to be shown until you reset the computer, it’s very unpleasant.
That exact same thing happened to me. Still, its pretty damn good for a 100% free Security System – using it and the Threatfire program [same company] is the best security solution for people who dont want to pay I reckon. Never liked AVG [coz a few years ago AVG failed to stop a virus from infecting my entire home network so i just dont want to give it another chance haha]. PC Tools is groovy tho, shame its a little funny in 2K8.
