Redirection to another links

[Crazytunaeg]

Hi , there is something suspicious after entering my domain, it takes seconds then suddenly it redirected to another website. This issue wasn't happening but months ago i shifted from shopify platform to Google website then i went back to shopify. After the last move this problem happened.

This is my website www.crazy-tuna.com 

This problem is not happening to me only, customers are facing the same thing.

 I have already verified with GoDaddy DNS and everything is configured fine,They told me that it may be a malware or something inside shopify website and they can fix
