Infected file re-appears after reboot

[SPD]

Anti-malware reports an infected file, that requires a reboot to be removed. After reboot, the file (or a new copy of it) is still present and detected on a new scan. The two logs are below, I am not able to copy the infected file.

I'm having the same problem. File is

"c:\windows\system32\drivers\wjphwxtd.sys (Rootkit.Agent) -> Delete on reboot."

However, I reboot and do another quick scan, and file is still there and I'm given the same instructions (reboot).

Just updated malwarebytes this morning.
