Q - question

AutoCAD displays: MUST re_cover!

A - answer Instead of the drawing contents, AutoCAD suddenly displays the text "MUST re_cover!" (or "MUST re1/8cover!").

This is the result of the acad.vlx virus! Please first delete any acad.vlx files which can be found in your AutoCAD support path. Do not open any other DWG files.

You can use the RE_COVER (not RECOVER) command in an infected AutoCAD session to restore the DWG file. See also the Autodesk document TS13717811.
