She was running Window 7 and had a problem after the last update. A clean install fixed her problem.Since we had no internet access, it was a good thing that I also carry a usb device with all the tools I needed to complete the task. The only thing I could not do was to register the program since that requires internet access. One more satisfied Avast customer.
