There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

The certificate is related to PortSwigger in case that means something to you.

Issuer CN = PortSwigger CA,OU = PortSwigger CA,O = PortSwigger,L = PortSwigger,ST = PortSwigger,C = PortSwigger

Subject CN = www.google.com,OU = PortSwigger CA,O = PortSwigger,C = PortSwigger
