Getting a pop up stating 'Symantec WSS Agent already running' while login on computer.
Unknown at this time. The wssa-ui.exe is started twice and the second execution is causing the pop-up to appear.
This is happening randomly to a very limited hosts (less than 1%).
WSS Agent 7.4.1
The pop-up will be removed in a future version of the WSSA (currently targeting 8.x).
In the interim the pop-up can be dismissed.
