FYI If you do not have a problem do nothing.
I am not sure how this virus happened or where it comes from; and hopefully the fix worked. It is very confusing.
After applying these instruction to M/S Office and it is working
M/S Office Error message:
“Microsoft Office can’t find your license for this application. A repair attempt was unsuccessful or was cancelled. Microsoft Office will now exit.”
Fix: All Control Panel Items (click), Programs and Features (click), Microsoft Office Professional plus 2013 (click), Change program (click) (Do not uninstall)
Selection: “repair” (run ?)
