com.cisco.anyconnect.macos.acsockext hogs Mac CPU but cannot be killed or stopped from launching. Nothing online works so far to solve this
Press Don't allow When Cisco asks Cisco AnyConnect Socket Filter” Would Like to Filter Network Content.
If you do so it creates Network Settings that automatically launches this CPU-consuming com.cisco.anyconnect.macos.acsockext.
To revert it :

Go to System Preferences -&gt; Network
Observe several instances starting with Cisco.. next to Wi-Fi
Delete all of them with - button beneath
Press Apply
If any Cisco instances appears again, delete it again; Press Apply
Check for com.cisco.anyconnect.macos.acsockext in Activity Monitor and kill it if needed
NEVER! Allow Cisco to Filter Network Content again
(for some reason it lacks of Don't ask again checkbox)
