I was trying to change the way that MS Office 16 handled VIEW. I followed the instructions on the site below and now I cannot change the formatting at all on docx that have been opened after the problem started. I assume this is a macro virus but K does not detect one in files or in normal.dotm. I have done the usual - reinstalled Office. Copied a clean normal.dotm, but the virus is hiding somewhere. Any ideas what to do?
