online-words on "[Plugin: Wordfence Security] My website is slow and once opened takes me in another website 'another domain'"

This is my website artboos.com
Try to visit it, and once it opened, you will find yourself in another site by another domain!!
I already checked about everything relating domain and it is okay, so WHAT IS WRONG! how can I fix this problem?!
Thanks in advanced.
