Please follow the instructions below to delete the corrupt definitions file, and restart your computer.
First you need to delete the broken definitions file.
Location: (2000, XP) - C:\Documents and Settings\All Users\Application Data\Lavasoft \Ad-Aware\core.aawdef
Location Vista: (Vista) - C:\ProgramData\Lavasoft \Ad-Aware\ core.aawdef
N.B. You will need to be configured to view hidden files and folders to find these locations, XP and Vista.
Then restart the computer and restart Ad-Aware.
Instead of restarting your computer, you can also restart the Ad-Aware service manually after you delete the corrupt def file.
1. Go to the start menu, click 'Run...' and type 'services.msc'
2. In the services window, locate 'Ad-Aware Service', select it and
3. When the service is stopped, click 'Start'
4. Start Ad-Aware again.
