I'm one of the developers at Lavasoft who is currently looking into this matter.
I assure you that we are aware of the issue and are working to fix it as soon as possible. The main problem is that we aren't able to reproduce the error on our own test systems which makes it very hard for us to locate the bug. If you are experiencing this issue we would love to get in touch with you and if possible have you run a special diagnostic build of Ad-Aware 2007 which will help us locate the problem and ultimately fix the issue altogether.
Please send me a PM if you are experiencing the error and would consider to work with us to try to resolve it.
you may contact me, i also have this problem, recent onset, worked okay before
i suspect someone out there has deciphered your algorithm
the program hangs up after cookies are identified as infections
i manually terminate the program, manually delete cookies, then run the software again, this time it runs to conclusion
this sequence has been replicated three or four times
i have also sought if there is other malware, via windows defender, and run symantic a few times, and also defrag, none of this solves this constant -run (hung, really, not running, stops at 'conditional' as others have posted)
