I received the notification from Bitdefender:
"An unauthorized app attempted to access your backups.
App: /System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd
We blocked the app to prevent it from altering the content of your backups."
I have no idea what this app is, how to remove it, and get my backup done. Why is this happening and how to I get things moving again? Please help. I have had Bitdefender for one going on 2 years and until today, when it prevented me from completing a routine backup, have had no issues. This, however, is very upsetting. I have no idea what to do and no clear explanation or guidance. I hope this forum can be of help.
