Hello, in KSC shows: “Real-Time Protection status: Stopped” on one device with Network Agent and KES

In Windows Event Log “Product ‘Kaspersky Endpoint Security for Windows' has stopped” message appears every 5 seconds.

I can not start application from Properties → Applications→ KES → blue RUN button with reason: “Failed to start application”

No new Events in Properties section,

How to debug that?

The KES GUI shows that protection is running, computer have a network connection with the server.

Thanks !


client PC with Win 10 PRO 2009 fully updated

Hi @dggbg 

The reason you cannot start and stop by right-clink on antivirus instance on Kaspersky Security Console 12 is not directly related to the problem with the Real-Time Protection status: Stopped, but with the synchronize communication between KSC and Kaspersky Network Agent.  

I propose the following solution :

Try creating a task to force KES to start or resume. More details you can have from the KB article:  https://support.kaspersky.com/KESWin/11.1.1/en-US/123304.htm

However, if the task is not succeeding, I propose to uninstall and reinstall as an approach to solve the problem. If the problem persists, don’t hesitate to contact Kaspersky’s support for further instructions by opening a ticket through the web portal https://companyaccount.kaspersky.com/



Hello @R.pine ,

creating a task - did not help, but manual uninstall and reinstall does, thank you, Best Regards!
