I am a beginner programmer who frequents hackthissite and hellboundhackers and require password recovery programs to crack hashes. But for some reason, Avast detects things like Cain and Abel and John the Ripper as PUPs. I added them to all the exclusion lists, and set the settings to "ask", but avast will always abort connection and make firefox have a download error. What can I do to prevent this?
