After using LNS and Outpost I have finally converted to a hardware firewall/ antivirus/ IPS system. All of the processes running on my system slowed me down too much. Now all is taken care of by a Fortigate 60. I would suggest to people out there running multiple computers get a centralized firewall instead. Now all systems are protected at the central location ... sooo much better. You can find these 60's on Ebay for around $400.
