With Webroots SpySweeper enabled AD-Aware SE will freeze during a sweep. If I disable SpySweeper, AD-Aware works just fine
I have been using AD-Aware for years,much to my satisfaction. The freezing problem began when I receintly upgraded to SpySweeper Beta. I am in the process of tweaking SpySweeper in an effort to resolve this conflict.

Does anyone have a suggestion ? Thanks.

Disable SpySweeper when performing an Ad-Aware scan. Anti adware, spyware, and virus programs all interfere with each other when running side by side, and so best practice is to disable something temporarily if it's interfering.
