Malware notifications on MacBook Pro

Dear Apple Community,

For the last two days, I have been getting this alert and by clicking OK it's coming again and again also when I clicked show in Finder nothing happened.

Kindly assist me with how to get rid of this thing and also I cleared my cache, logs did first aid in disk utility as well.

I will wait for the positive response anxiously.
