I just let BitDefender scan my system and it deleted two joke programs that I knew I had on my hard drive. They are neither in quarantine, nor in the Windows trashcan.
Luckily I found them on some websites again.
To prevent this from happening again, where do I tell BD to keep these programs or at least move them into quarantine? I didn't find such an option in the settings.
Having BD delete files right away without warning is an unacceptable behaviour.
