Computer Monitoring Error

Recently - probably the last couple weeks? - I’ve been notified that I have a “Computer Monitoring Error” on my desktop. This is a message from the server. I’m not sure what it means, and when I check - everything seems ok.

Am I missing something? Is this a false warning sign?

You can look at this, but I think it is something else I can’t remember. Windows updates I think
