I am using AVG network edition, at the suggestion of Bert. Fairly easy to manage. A little tricky to set up but, even with my very, very limited networking experience, I was able to "push" the program out to the clients from the server. I tried Norton's first and hated it. It really slowed my network
( which runs SB 2003)down and was hard as heck to remove. This is where my IT guy and I parted ways. When I told him I wanted to go with AVG he tried downloading it to the server but could not so he gave up. After a little investigating I figured out my server had not been doing regular updates...was still using Service Pack 1!!! So, I found help online, downloaded the missing file which then allowed the normal updates to occur, updated the Service Packs and AVG went on without another hitch. I recommend it. Thanks, Bert.
