Auto-Protect Failed to remediate the infection. What to do?

Hi,

We have SEPM 12.1.6 MP5 running in our environment and SEPs are on 12.1.7 version. On one computer we have infected file and SEP is saying "All action failed: Auto-Protect". What can we do remedy this situation? I have attached the actual notification we are recieving. Can anyone kindly guide me?

Thanks.
