A NetNavi Recovery Program is the anime equivalent of healing chips. They can check to see if new, unidentifiable data has been entered into a Navi's programming. Dr.Hikari used this on MegaMan.EXE, and found Double Soul. He needed to be rebooted. This is true for all Navis in these that have been excessively damaged. It is unclear if Anetta's Navi, Silk.EXE, was put in one of these, because if she was, she'd be a LOT more happier, which she was In Rockman EXE Stream episode 44. This implies that Anetta is not so depressed, so she may have Silk back through Mr. Famous's expertise in the NetNavi Recovery field.
