Thanks for clarifying this for us!Unfortunately, my corporate life requires us to use that other virus protection package that begins with an
M...

With that, I'm also licensed to use it on my home network, but choose to only run it on my servers. All Windows 7 boxes are running Avast! Free. Love the product and get everyone I know to switch.

Yes, that's correct... I'm running multiple servers... and I'm running a number of Windows 7 systems.

All of which are in AD. I'm not on some
estate, but I do take full advantage of RSAT, Active Directory (
thank you MSDN subscription), and VMware. Our photo, music, and movie libraries are all centralized, and SharePoint is what we use for our file shares and family planning/scheduling, amongst other things. To top that off, the kids can only log onto their systems under specific time restrictions, and have limitations on what they can do to their PCs and where they can surf.

Basically, my home network is a test bed. The family are my guinea pigs. My wife has a PC and laptop, each of my kids have PCs, I have a PC and laptop (besides the work laptop that has that
M product on it), and we have a couple of PCs that are dedicated Windows Media Center boxes attached to TVs. In addition, there's a PC set up in the guest room and one in the kitchen. All are on the domain and all are centrally managed.
All have Avast! Free. 
... and yes... all have this message popping up. No biggy now!
