Cons: Ad-Aware Free AntiVirus has the slowest scan engine of any AV program I have ever used. It doesn't scan email like other free AV programs do. It doesn't allow you to choose folders to ignore while scanning, that would speed things up. Just doesn't have the basic features that other free AV programs have. Ad-Aware Free AV has a lot of work to do to compete with other free AV programs.
Other Thoughts: Needs more basic featurs....
