Well, I have fixed the problem by replacing those two files with the original ones (thankfully they weren't redesigned files that I have edited) so it's not necessary for me to put my site URL up. But, I am with Cirtex Hosting sharing a server if that helps.
EDIT * Basically, I'm just trying to let people know that hackers DO hack, and I don't want other people to find they're files have been overwritten without a backup. Also, I am looking to see if anyone knows of any ways to prevent such attacks for the future.
