I am using Ad-Aware 2007 7.0.2.5 (free version) on Windows XP-Pro.
When I launch it, it detects more than a 100 infections.
However, it keeps running for more than 3 days without completing.
It is stuck in step 2. I had to kill it using Task Manager.
So I am not able to delete the infected items.
I have tried this few times in the last couple of weeks without success.
