Bitdefender constantly saying I am being attacked by vssadmin.exe malware

I have tried to delete. Search online on how to remove it. Most of the advice online is to install their dodgy product or run their dodgy programme.

How can I remove this malware ? Is this 100% malware or is this a false positive?

Thank you so much for any help. I would really rather not reinstall the computer but will do this if this is the best option.
