how to stop address from forward

hi guys and girls

my site was attacked so I had to do some fixing up

the address is http://www.parx-e.com but I stupidly added some redirection code in to .htaccess

my question is how do I stop http://www.parx-e.com from going to parx-e.com/parxe

when I just want it to be http://www.parx-e.com not parxe.com/parxe where the blog is located

if you can help would be much appreciated and yes I have set Site Address (URL) to be parx-e.com
