Bitdefender pop up error at restart

Every time I reboot my laptop (windows 10 pro), it does the normal 'restarting'
then I get this pop up. If left alone it goes away, and the laptop restarts.
The file BitDefender Threat Scanner.dmp in is not readable in notepad.
Any suggestions on resolving this?
