Are you able to see the logs when you log in as an Admin?

If the ans is No , then run a repair for SEP Client

Also tell me what  is the vesrsion of SEP and are you getting any errors in the event viewer

Any process that is taking High CPU in Task manger ?

Hello,

If you are not able to view the logs on the SEP client if you are logged in as a non-admin user then that is by design. By default only admin users are allowed to view all the logs on the SEP client.

i hope this is helpful :-)
