Virus Infection Found report on MacBook Lock Screen

My MacBook Air M1 running MacOS 12 Monterey suddenly started showing message "Virus Infection Found" on the Lock Screen (Screenshot attached).

Though I tried to scan my mack with Norton 360 a number of times, I am not yet able to get rid of this message. Norton 360 scan says "No virus found" on completion of all types of scans.

I am getting more and more worried over this and request the community and experts at Norton to resolve the issue.

Someone had put that message in the lock screen without my knowledge and it was a prank.
