The site is http://www.jpshealthandfitness.com.au/blog/.
When you enter the site directly into the address bar it works fine. However, when clicking on a link from facebook or google search results it redirects to a random domain that changes each time.
It's unusual because the links work for some but not others.
I get the feeling it could be malware but I'm not sure where to start. Has anyone experienced this before and knows how to fix it?
Thank-you in advance.
