the place where it stalls is
CLSID\{FA41A3BA-5978-480C-9D9F-70ADC1DE4590}
if that is of any relevance.

I am a new user. Not sure what else to try.
Thanks for any suggestions.

WLee,
The appearance of hanging usually occurs when 'Scan archives' is selected. Its not actually stopped scanning however. What's happening is Ad-aware is de-compressing/ unzipping files to check the contents for suspicious files, the Ad-aware re-compresses the files. This can take some time.
If this is the setting that's effecting your scans,
Try this
Open your Ad-aware,
Click the "Settings" (The Gear) button at the top right to display the "Settings" main menu.
Click "Scanning".
Un-Tick 'Scan within archives' and
then Click on "Scanning Engine"
then un-Tick (un-check) "Unload recognised modules during scan"
then Click on the Proceed button.
Also try shutting as many programs/process as possible. (I.E firewall Anti-Virus etc.) Please make sure that you
Unplug/disconnect your Modem before disabling your Anti-Virus/Firewall
Just remember to turn them back on
Then scan with Ad-ware by doing a "Full Scan" (Custom) and post your logfile here by using the "reply" feature,
