UPDATE: The following post is outdated and the best solution can be found in my new post about AVG
AVG8 is has a really nice, new, and organized interface. The control panel and virus scanning are all under the same screen, except for virus vault and history log which are popups.
AVG8 has a new feature called LinkScanner which puts green checkmark stars next to your search results on sites like Google. This is to verify that a link is safe. You can also report links. However, I think it is rather annoying and intrusive. You can disable LinkScanner in AVG but it will constantly warn you that you may not be protected.
