Site's been hacked: meta descript have been change & redirects on mobile phones

My site has been hacked. My meta descriptions have all been changed to “Cheap luxury handbags are all sale on our website. There are so many beautiful Louis vuitton ,Gucci ,Chanel ,prada ,coach , Hermes ,Miu Miu handbags for you .” (prior to that I did not have meta descriptions). The hacked meta description is present in Google search results when I use a mobile phone or laptop. However, when I’m on a mobile phone and search for my site on Google, it redirects to http://www.luxury361.com. The redirect does not occur when I use a laptop.

I’m running the most up-to-date plugins and version of WordPress. How can I locate the hacked code and how do I remove it?

Thanks,
