I'm working on an AAC setup that scans for AV version before allowing logon. However I'm finding it to be a bit of a mission to locate and install trial software for all the different types of AV packages out there. Does anyone know of a website that lists the latest virus engine version and signature so that I can just plug the numbers into the AV scan? If not is anyone interested in starting a webpage that we keep up to date with the latest info to just plug into AAC. I currently need the version info for: McAfee Virusscan (home version) Norton AntiVirus Personal Trend OfficeScan I've also purchased additional EPA factory scans for eTrust, AVG, F-Secure, Trend. So I'm going to try and keep these up to date along with the standard Citrix provided AV scans. Matthew Shrewsbury, MCSE+Internet MCSE 2000 CCA Server+ Network Manager
