[Hoch CPU Last von Outlook bei laufendem KES auf macOS BigSur]

Thanks, Hansaplast.  This workaround worked for me.  Obviously this change diminishes the level of protection the product offers, but I’m pleased at least to have some level of protection and have a usable computer.  I look forward to Kaspersky releasing a fix for the issue.

Thanks, Hansaplast.

Version numbers are:

• Kaspersky Endpoint Security for Mac 11.1.0.210a

• macOS Big Sur 11.5

[Hoch CPU Last von Outlook bei laufendem KES auf macOS BigSur]

I am having the same trouble after recently upgrading to Big Sur.  Apologies I can only reply in English.

• macOS 11.4
• Outlook 16.51
• Kaspersky Endpoint Security for Mac 11.1.0.210a

While Kaspersky is running, Outlook uses 100% CPU and a constant stream of the following messages appear in Console.

 

When stopping Kaspersky by doing the following, utilisation drops back to normal levels.

sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.kav.kavd.plist && sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.klnagent.plist && sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.sysextctrld.plist 

Upon restarting Kaspersky, CPU utilisation hits 100% again after a few minutes.

Uninstalling and reinstalling KES did not fix the problem.  Disabling protection in KES preferences did not fix the problem either.

I am having the same issue after having just upgraded to Big Sur.

• Kaspersky Endpoint Security 11.1.0.210a
• Microsoft Outlook 16.51 (21071101)

After KES has been running for a few minutes, Outlook starts using a constant 100% CPU (give or take a few percent).

Opening up Console.app shows a continuous stream of the following messages:

 

Process: Microsoft Outlook (libnetwork.dylib)

nw_socket_handle_socket_event [C145.1:1] Socket received READ_CLOSE event

 

When killing KES, the messages stop appearing in Console.app and Outlook CPU usage drops off entirely.  Upon starting KES and waiting a few minutes, Outlook CPU usage again hits 100%.

 

Here’s how I'm killing KES

sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.kav.kavd.plist && sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.klnagent.plist && sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.sysextctrld.plist

Unchecking ‘Enable Protection’ in KES Preferences does not fix the problem.  Uninstalling and reinstalling KES did not solve the problem.

Apologies that I can only respond in English.

 

Here is a screenshot of the console:
