I'm still testing the new Ad Aware 2007, so I haven't decided how good or bad it is yet. The one problem I did have was fixed by updating it to version 220.127.116.11. The initial version released wouldn't allow me to scan and generated an error. After updating, the problem was gone. There's also an update to the part of Ad Aware 2007 that downloads updates. I definitely recommend updating to version 18.104.22.168 if you are getting error messages or are having problems.
