Hi,

 

1.     Do you receive the popup at the startup (after the computer started)?

2.     Have you made any changes to your computer prior to this issue?

 

 

Method 1:  Place the computer in clean boot and see if that helps.

Refer:

Note: After you have finished diagnosing, follow step 7 in the article to boot to normal startup.

 

 

 

Method 2: Run SFC Scan.

Refer:

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
