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.

@Fernet Network Agent and KES_Linux are not built into the same installer, so they are installed separately.There is no sequence you have to follow when installing the system. However, a best practice recommendation would be you install the Network Agent first so that the machine can sync with the KSC, thus making the antivirus installation somewhat easier.
