Just use ResEdit or any of the usual apps to make it invisible again.
Don't delete it - it will prob be put back anyway. It contains the graphics for personal web sharing - when someone access the site, it has the icons for files and folders, etc, like at ftp sites, get what I mean?
However deleting it shouldn't do any harm.
UPDATE: After considering this further, making it invisible might not be such a good idea either - in the Finder, one cannot access invisible items, or items within an invisible folder, and so on. So maybe it would cause problems. I dragged a folder with invisible items to the Netscape window and was able to access them, so it probably won't cause a problem, but in case it does you know where to start troubleshooting.
