I too uninstalled it. I have a ridiculous multi-core system with more RAM than anybody really needs; I have been unable to even mildly slow it down since I built it -- until I installed AVG, which slapped ridiculous scan bottlenecks on every disk read, every download, every link click, every application launch, every thing I could do on my box.

It's almost worse than actually having a virus. At least you can uninstall it. Now my machine is back to it's usual, quick self.
