Hello,
I am sure the Clients may be managed (still assuming)
However, I have some Questions.
1) Is this Happening on All machines or only on 1 machine?
2) What version of SEP is this?
3) On what OS this has been Installed?
Incase, if this is happening on all machines, please follow the steps below and check.
1) Login to the SEPM
2) Click on Clients, Highlight the Group the machine is reporting to.
3) Click on Policies Tab, Click on Antivirus and Antispyware Policy,
4) Click on File System Auto-Protect
5) Check if the Policy is enable or Disabled.
If in case, it is disabled, the AV/AS policy would turn it self off.
