I have been using BitDefender for about five years now. Switched to it when a nasty rootkit tore right through Norton on a network I was supporting. And, found I really liked that it wasn't the memory hog Norton has always been.

One of the best features is their Network Mode. It allows you to control the settings on all computers globally from one computer, without having to run around setting every computer individually.

They have package deals for multiple computers. Current package deals are $49.95/3 computers/year for Internet Security and $79.95/3 computers/year for Total Security.

There are a few minor differences between Internet Security & Total Security. Total Security has a tune-up and file shredder. Total Security also offers a small amount of online storage with scheduled backup.

Here is the link to their comparison page:

I use Internet Security for my home network, and Total Security for the one network I still support.
