    How do I scan .jar files? None of these methods work for .jar files. I made a RAT infected .jar file and it wasn't detected.

    These methods do work for .jar files. However, keep in mind that they are not 100% effective. This is especially the case if you made the RAT file yourself and it has never been seen in the wild before.
