Recently running the program I get a message that states: Your definitions file has been compromised. Please delete your definitions file and restart Ad-aware. The it supplies the location of the def.ref file.
I delete the file and run Ad-aware. The next time I run it, the same message appears. What could be compromising the definitions file?
I also have installed and run, but not at the same time a program names Avast! AntiVirus.
