I have been testing some new software. A program from P C Tools, called ThreatFire ( www.ThreatFire.com ). It is suppose to supplement your installed anti-virus program. It was suppose to provide "Behavioral Virus and Spyware Protection" for known and unknown virus, trojan, worms, rootkits, buffer overflows, and spyware, before a virus definition actually comes out. It also had a anti-rootkit program in it. I can not actually say that it works as I had no detected rootkit infection. This program was previously known as CybeHawk by it's previous owner. This program will only run on 32bit and is not compatible with my two X64 machines, so could not test it on one of them.
Unfortunately a few of my players were complaining that the server has been lagging lately. So I have uninstalled ThreatFire for the time being. I will evaluate weather things improve and post my results later, as a add-on to this post.
