After the last AVG update I can no longer save my old Excel files, if I created new ones, those can be saved. I am getting this message:
When saving a file, a sharing violation can be caused by the way an antivirus application interacts with Microsoft Office.
Check with your antivirus provider to make sure that the current version of the application, including updates, is installed. The antivirus provider might also have information or solutions for sharing violation issues.

I am running Windows 10 on an Acer Aspire M5-583P computer. 

Does anyone know how to fix this?
