I do a manual search every day for my various spyware and anti-virus programs. To as I tried to pull up Ad-Aware to look for the updates I got the following error message:  " Your definition file has been compromised. Please delete your defintion file and restart Ad-Aware. C:\Program\Files\Ad-Aware SE Personal\defs.ref."  There was an OK button, which when pushed then brought up the Ad Aware front page and I was able to search for any updates as usual. Just wondering if anyone else has received this message, and just running it by the board about how to proceed. As far as I know the only way I can delete the defintion file is to remove the program and reinstall it. Thanks as usual for any insights.
