This happens when you have installed a theme/plugin from an untrusted source (ie. nulled script).
It's normal that nulled (themes/plugins that are downloaded illegally) contains malicious code inside them.
Nulled theme/plugin basically mean cracked/hacked. The distributors of such themes/plugins often hide popups/ads inside to earn money or manage your database and files or any other purpose. They aren't secure at all, and it is not worth using them.
So what is next?! I suggest you to use latest PHP version 7.x (in your case you have it) because it doesn't allow "eval" function to be used which will reduce chances for this "virus" to make things worse.
Install WordFence plugin and perform a site scan to see if there is anything suspicious left.
If the WordFence results are fine, then you can proceed with installing the plugins and themes, please note that you need to install only from trusted sources. If you have downloaded a plugin or theme from an unknown/untrusted source then don't install it.
From mobile, it redirects to a different site, see attached file
Hi mihaelasipos,

Re-install the copy of WordPress:
(view large version)
Install WordFence plugin and perform a site scan to see if there is anything suspicious left.
If the WordFence results are fine, then you can proceed with installing the plugins and themes, please note that you need to install only from trusted sources. If you have downloaded a plugin or theme from an unknown/untrusted source then don't install it.
After that your site should be available again.
I hope this will help you.
