Hi,
I went through your website redirection occurrence. I noticed that https version of your website is redirecting to http version to some other website. It can be achieved by .htaccess or through web server.
Here, the first step you should take is to contact your web hosting provider. Make sure that you are not sharing an IP address on port 443 with shopingmarket.com (however, it is not possible without having control panel/DNS panel details).
Also, scan your website with anti-virus software for any malware injection. If possible restore your website from available clean backup.
Thanks,
