Terminal Sever & Antivirus question

I have a TS box and I'm using AVG server edition for AV.  The problem is each of my users logs in and random virus cans start up.  At any one time, I find that I have 10 to 15 usrs running AV scans and each one is using up about 8% of the processor.  Of course, my processors are running at 90 to 100%.

My question is, how can I install AV software so that it WILL NOT load with each profile?

I only want AV to run on the console and not load into each profile.  I tried removing the AV software and installing while NOT in install mode, but that didn't work.

Any ideas on how I can allow AV to run at the console and not within each profile would be greatly appreciated.

Thanks
