Hi,
I tried to show js problem at my https://streamgeeks-rebranded-dev.cloudns.cl/ site
located at AWS, ubuntu, 20 Apache/2.4
But I got a feedback from one of users :

My connection block that site ^^
The security system of the network operator blocks me saying that it is "a possible malware" –

After discussion I got link :

and got some errors report :

Avira (no cloud) Phishing
Netcraft - Malicious

Which steps have I to take ? If it some bad code inside of my site ? Or something wrong in ubuntu 20/apache/mysql ?


Also are there some apps/tools for my Kubuntu 18 on my laptop to see these problems working with my site ?

Thanks!
