My WordPress site redirect to Basket Ball justin bieber youtube video

Hi, I have an issue and it is my website made with WordPress sometimes redirects me to a video on YouTube of Justin Bieber (Basket ball). Does not pass always, and sometimes when I opened my site through bookmark tab or crawling on website menu.
I have the latest version of WordPress. When I installed these plugins, my problem was solved, but now, three weeks later, it happens again or never stopped, just did not happen to me more..I don’t know.
What can I do to remove this issue? Please… Sounds like a joke, but it is not. I am using the following plugins

Akismet
Contact Form 7
Fusion Core
Hello Dolly
itheme security
Layer Slider WP
Really simple Captcha
Revolution Slider
w3 Total Cache
Wp-lefooter
wp-smush.it
