I hope you find a solution to this problem.

Make sure the web browsers F12 Developer option is disabled and cannot be used. Not a fan of some browsers having this set to enabled by default.

I'll do some research on the information youve mentioned

Ok, i have done a little research from the first address you added.

From my findings, im thinking this is something to do with your email system, an unsecure email from bullyboys Amazon Technologies Inc / Amazon.com using the cloudflare.com / cloudfront.net through the gmail system.

I can tell its through gmail from the whois and domain searches ive done time and time again, plus some abuseip database searching.

Something got through your email system either spam or junk.

I will keep digging
