Microsoft office home and student 2007

I completed an online support with AVG this morning to clear a virus and then I could not open any of my microsoft documents. How can I fix this?

Hello Kim.
I understand that this could be disappointing when you are unable to access your Microsoft docs. I request you to disable AVG and check if you are able to access them.
If you are able to access the docs after disabling AVG, I request you to update the Microsoft Office and recheck it.
Please let us know the status after following the instructions above.
Thank you.
