Word - turning off setting for track changes

[elidadesigns]

Hello,

I recently upgraded to Windows 2013 and have the new version of word and everytime I open a document, the "track changes" is default to "on" in my document so even if I switch it to "original" and they go away and I save the document, next time I open it up, it's back on. Lots of red notes all over the place and pdfing is impossible. Help?!! Could it be a virus?!
