Disturbing messages appearing on my Mac before logging in

Before I log in, a banner appear with disturbing system messages. Messages vary but basically they warn me that my system has been hacked. However, as once I log in, the messages disappear and my Mac operates normally. I've run Bitdefender many times without detecting any malware. Some how, I must have picked up some app that producing these disturbing messages. Does anyone have an idea how to get rid of these messages?

iMac 27″, macOS 12.6
