when I click on wp-admin/users.php in the panel of my website, in the "Search users" button, appears the site in basic code and when I click on any link there is a download window and I can not enter the website.
The download window comes from the http address: http://tecros.ru.
In it appears a php archive called index.php
This is happens too when I click on any link to my page from Facebook or Twitter.
Please help me!
