One of the first things that malware attempts to do during an attack is to disable your system security software. To prevent services and files from being stopped or modified, configure Self Protection.
Caution
Disabling Self Protection leaves your system vulnerable to attack.
Select Menu → Policy → Policy Catalog, then select Endpoint Security Common from the Products list in the left pane.
From the Category list in the right pane, select Options.
Click the name of an editable policy.
From Self Protection, verify that Self Protection is enabled.
Specify the action for each of the following resources:
Files and folders — Prevents users from changing the Trellix database, binaries, safe search files, and configuration files.
Registry — Prevents users from changing the Trellix registry hive, COM components, and uninstalling using the registry value.
Processes — Prevents stopping Trellix processes.
Click Save.
