Users being redirected to google

If I send a user a link to my website they get redirected to google with a quick flash of a url of “” before going to google.

I can get to my website, but when I go to my contact page and hit the “back” button (which is just an anchor tag to the home page) I get redirected to google too.

Is this something on the server at dreamhost or something else going on?[hr]
Another symptom:

when I type in my domain name without the www, I can get to it. When I put www in the url, I get the redirect to google.

It sounds like web site has been compromised, most likely due to an vulnerable application you installed being exploited.
