Don't like Ad-Aware personally....Years ago I used to to Ad-Aware and purchased a "Life Time License" but that "life time license" only lasted until they came out with another version so I think I got screw'd on that. I can no longer trust LavaSoft and I will never recommend them to anybody
I haven't used Ad-Aware in like... 6 years or so lol. Used to use it along with SpyBot.. now I just use: Initial manual removal of files (if necessary) -> MBAM Quick Scan -> ComboFix -> HJT -> TDSSKiller and/or Panda Anti-Rootkit -> MBAM Full scan ->AV scan.
