PUP.Optional.NetFilter, C:\Windows\SysNative\drivers\mrxsmb22.sys

Rebooted to delete. Ran adw again, above mrxsmb22.sys remains. So location is wrong. Checked location, does not exist.

Ran Copernic Desktop Search & OSForensics, neither found, both claiming file does not exist anywhere in my entire computer?
