I’ve experienced this too some days ago. I am using WP 2.0

I uploaded a new index.php and also the wp-admin folder, which had been removed! I also changed the password for the database etc.

My database content seems to be untouched (as far as I know).

I also had the same problem with my RSS feed, but I’ve just found the following simple solution:
Change line 87 in wp-blog-header.php to:
@header(a€?Last-Modified: a€?.$wp_last_modified);
instead of:
@header(a€?Last Modified: a€?.$wp_last_modified);
