AVG Corrupted office files (windows 10)

Thank you for your reply,

I ran PC Tuneup and have already reverted the changes but that made no difference. Documents created before I installed AVG seem to still work. But any document saved not to the C: Drive corrupts and are unable to open in office.

I downloaded AVG anti-virus free and subsequently did the lengthy PC tune-up.

Since then I have found that all word and office files become corrupted if you try and save them onto a new device such as a memory stick. If I attempt to email these files to another computer they also become corrupted.

Why has AVG done this and can it be fixed?!

Thanks
