Ad-Aware

A bad adware/spyware scanner that started out great years ago as "Ad-Aware SE PERSONAL" and slowly went bad to Ad-Aware 2007 and 2008. Decent detection of spyware but consumes too much memory and resources. Bad customer service, bad GUI, and extremely large for what it does. Secretly has a process running in the background and acts more like spyware than removing spyware. Takes forever to scan and doesn't usually finsish, instead it freezes and you'd have to start over.
