I have a reseller account. but sometimes, somthings goes wrong on my websites. I think server is hacked or DNS server is hacked. I searched similar content on google, then I found same HTML codes on hacker websites. Explaining the problem: mydomain.com is active everytime but sometime, floowing code is appeared. Please note that I have not this page or similar materials on account. Whether my domain contents is empty and only images folder is exist.
