It might not be a bad idea to read through Ad-Aware Freezing at Castle Cop's Lavasoft's AAW Forum.
It may help..
I have had the personal build 1.06 for almost 2 years and have never had a problem with it. I just renewed my Norton Anti-virus and now when Adaware gets to scanning local memory c:\Program Files\CommonFiles\SymantecShared\SecurityConsole\NSC_Wit stops scanning. The program is running in the task manager and I left it on for 10 minutes to see if it would start again but nothing happens. I also updated the defintions I tryed running a full scan but it was the same. I also get the timer icon except to stop the scan. Do I need to unistall and re-download again?
