Just a clarifying note from Lavasoft Support:
"Ad-Aware is not compatible with Norton 360 and it will conflict with Ad-Aware so in order for Ad-Aware to work properly you need to uninstall Norton 360

Ad-Aware is a great, free program, however, I'd be remiss in my comment without mentioning that it's become bloatware in the past years. Perhaps it's just a sign of the times: The more idiot, cyberspace jerk-offs, the more the necessity to write "heavier" software.
But what do I know - I'm just a musician, and we all know what they say about musicians: "He's a musician".
