Hi
I am new to the forum, and came seeking a solution to this very problem.
I am having the exact same issue, with Ad-Aware 2007.
Ad-Aware throws an 'Eaccess violation' whenever I attempt to start the program.
This is on a brand new 'virgin' OQO 02, XP Pro SP2.
I ran full scans with Spybot Search & Destroy, Nod32, and AVG Anti-root kit, all come back with 'no problems found', so I do not think it is 'mal-ware'. Also Spywareblaster is installed.
I set DEP to ignore Ad-Aware, but the problem persists.
I de-installed Ad-Aware, rebooted, used CC cleaner, rebooted, used CC-cleaner again, rebooted, re-installed Ad-Aware 2007, and the problem still persists.
Maybe an application bug?
