The x10deu.rsc file is a X10RES file which is a part of ATIX10.  It was created by ATI Technologies, Inc.  Although it originally comes from a legitimate source, the x10deu.rsc file may still be found cropping up as an error message in some cases.

This is not because it is a computer virus designed to ruin hard drives, but it is still possible that it could render your machine unusable.  Because of this, we recommend a registry scan with a reliable and respected registry cleaner.

Undergoing a registry scan can help to identify whether or not the x10deu.rsc file is causing trouble for your computer, and a good registry cleaner can even help to fix the problem.  One of the best sources for a registry cleaning service comes through ZookaWare PC Cleaner, who will allow customers to complete a free initial scan to determine whether or not their services are even needed!
