What I did to slove problem

  1. In wp-include directory, delete wp-vcd.php and class.wp.php files
  2. In wp-include directory, open post.php and detele first php tag added by Malware.
  3. Open to theme’s functions.php file, and delete the above codes.

This should stop popups. But I don’t now how long it works.
