Hallo SpyDie
It's simply a Yahoo Search Bar. (works in the same way as Google toolbar etc. do, but I imagine AVG get something out of the customers installing the toolbar and using it)
I haven't tried AVG 8, but I've seen screenshots and the GUI is totally revamped. Looks nice.
... It works fine, and my wife are pleased with it.

So, it was Yahoo! Thanks for telling! - I really did wonder if we said "No" to something we would have said "Yes" to.
(But I did ask my wife)
- Well in that case it was good we said "No".
... I did once install Yahoo Search Bar, when I installed CCleaner (as far as I remember - forgot to un-mark).
And it was difficult to erase the "bar" again.
