Information in this article can be used when there are disk space limitations imposed on the folders used by KESL:
/var/opt/kaspersky - default KESL installation folder
/tmp - default folder used to store temporary files during the scan

To move files located in this directory you can create a symbolic link to another folder before installation. Use the following steps:
Before installing KESL:
The Application Control component has a category called Browser extensions. There is a known limitation for it in Chrome.

It requires an .exe file to load. An extension that is already running cannot be blocked by application control (it h

Solution
To resolve this problem you need to make sure that services start in the correct order.
For Systemd systems:
1. Create a file /etc/systemd/system/kesl.service.d/override.conf
