WordPress displaying pharm ads but I can't see them

I was wondering if anyone can help. I was looking thru webmaster tools and I notice that my top keywords were pharma keywords so I investigated and I found something interesting
For my site https://www.uppe rhost.com/blog/category/blog/page/10/ everything looks normal but when I go to https://webcache.googleusercontent.com/search?q=cache:AkxjuyWW60oJ:www.upperhost.com/blog/category/blog/page/10/+&cd=1&hl=en&ct=clnk&gl=us&client=firefox-a

That is the google cache. I don’t get how that happen because everything I go thru my pages to make sure something like this doesn’t happen. I also always update my wordpress to the latest version. I appreciate any insights to this matter

Also, is wordpress ok right now? I can’t tell if it is still hacked or not
