Would something like this hurt my rankings?

When I site: my domain in Google there is another domain also there

[interlink]

I have no idea if something like this would hurt my rankings. However my rankings are very low and I am trying to find out why. I have a decent amount of links, however that is a complete other topic.

When I go to Google and do a search for all the pages under my site, I get another web page from another website included in the results. It is in the top few results very often. All of the other results are pages from my site.

I tried to e-mail Google several times and I got the same answer each time. Is there any way I can get this page removed? The page is a Supplemental Result, but when you click on it, it redirects to their website. I am so confused and have no idea what to do. I would greatly appreciate nany opinions on this.

I've never actually seen a real one before until this time, but you my friend appear to be....

302 REDIRECT HIJACKED

I did a google search "site: yourdomain.com" and someone else came up on the top, this is a problem.

Read this thread on fixing this and I hope you can make it work for you:
