Ehm... thank you but some more technical views?

The AV works fine and the Security center is OK, but something is not correctly registered for Vista/Win7 beyond that...
It's a detail and only a few programs notice this but I think Avast should support all the features of the new OSes better.
I'm sure it's quite trivial to fix, but you need more documentation about that (I'll see what I can find also on Technet)...
