You are trying to remove the Symantec Data Loss Prevention (DLP) Endpoint Agent from a MAC Catalina system and getting the following error:
"Uninstall_agent can't be opened because Apple cannot check it for malicious software"
Gatekeeper is blocking the uninstall application
To resolve the issue perform the following steps:
1. open terminal
2.sudo spctl --add <path to uninstall_agent>/uninstall_agent
3. Try the uninstall again which should now complete.
