My Outlook 2007 locks up when opening emails with lots of graphics in them. The problem seems to go away when I close Ad Aware from the system tray.
However, no matter what I do , Adaware keeps reloading itself. And, not matter what settings I make, it keeps starting each time I reboot my computer.
any suggestions will be appreciated.

2 suggestions: first, archive your old email. A lot of people's .pst files get ridiculously large. Outlook loads and runs much better when it's manageable.

Secondly, make sure you only run 1 real-time program running. I have Ad-aware, AVG and Win Defender all with real-time capability, and I had a lot of lag time - once I turned off 2 of the 3, my system's much more responsive. If you want to turn off Ad-aware, go to Settings > AdWatch! Live > General and uncheck all modules. Next reboot, Ad-aware won't load automatically.
