Hi John,
With AAW SE, did you ever detect anything other than cookies or MRUs?
I only did once (in nearly 8 years), after my nephew had managed to get on my system without my knowledge (

) and AAW cleaned a mid-level threat for me.
I have been using AAW 2007 Plus since its release and have only ever had a very occasional tracking cookie - since I am (now) the only person with access to this PC, I don't bother to scan for MRUs, as already I know which apps I have recently used.
I also use a "layered approach" to security, with regular scans from other security software (turning off the real-time component of Ad-Aware 2007 Plus when I do so).
Regards,
Spike
