The fsck cured the problem. The problem files were removed by fsck during its recovery/rectification.
The first thing you should do when you find files or directories is use 'lsattr' to check the attributes.
The OP already did that.
You can use the 'chattr' command to change the attributes with something like 'chattr -i /bin/ps' to remove immutable attribute.
The OP tried chattr, and reported that it failed for certain files. This is why other people suggested an fsck; these are both indicators of a damaged filesystem.
