Redirecting to another site

Hi All
Thanks in advance for any help.
The site im needing help with is http;//www.wyldecrestparks.com

I was browsing the site on a samsung galaxy tab 2 earlier and when i tried to go to the site either directly or via google it was redirected to various other sites, all scam type sites.
If I change the settings on the tab 2 to use desktop and not mobile sites all is fine, ive tested it on three different android mobile solutions all with the same end result. Im redirected away from the site. All desktop seems to be fine.
Ive spent a couple of hours going through the header code and index page but I cant see anyting. The theme is a paid for theme from a reputable company and was edited by someone I trust. The only third party interaction is with various pluggins, but we try and only use those with a good rating and review.

Any ideas would be great. Thanks
