Hi All

Yesterday all files where fine, now today they all have a extra extension on them. The files should be "filename.xlsx" but are now "filename.XLSX.QFQZAHN. The file type has also now been made QFQZAHN. I can make the file type an excel file again and get rid of the extra extension but then the file is just random characters. I have tried to open and repair but the same thing happens. Cant read the info in the doc.

Please any help will be awesome!

Kind Regards
