Hi, When saving an excel document I got the following 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 even signed in again in excel, but the same message remains.

Can you tell me what to do ?

I did the AVG update, restarted my computer but I didn't succeed to save the excel file.

Hello Veeramani,

I tried to turn off the AVG internet security like suggested and now I'm able to save the document.

Like you indicate, this problem will be solved by one of the following updates, I hope :-).

Thanks for your answer, it was really helpfull.

Have a nice evening !
