There is a typo in my original post. The line of code I need to remove 
begins with...

<?php /**/eval(base64_decode(

Note the addition of /**/ to the line. When I add this to the sed 
command I get an error...

sed: -e expression #1, char 15: unknown option to `s'

I assume this means I need to escape the /**/ somehow but when I pu \ in 
front of / I get a different error...

sed: -e expression #1, char 40: Invalid preceding regular expression

How do I get past this?

Thanks,
Rick
