I cannot backup my MacBook with Time Machine. Have I some malware or something in MacBook?

Bitdefender blocked backup operation, and noted:

"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 scanned that backup file, but Bitdefender announced there is no malware in that "backupd"-file.
Have I sam malware in my laptop or not, an how can I find and destroy it?
