Today I scanned my computer with Avast Free and finally told me that some xcell files from Microsoft Office cannot be scanned or are corrupted. I gave apply move to chest by mistake and now when I want to open them it tell me:" The drive or network connection that that the shortcut is unavailable. make sure that the disk is properly inserted or the network resources is available, and then try again". And my Local D is blocked too. We urgently need to open those files. What to do? Please help me.
