Hi, I rolled back from Windows 10 to Windows 7 but couldn't get pages to open online. Wireless seemed fine. Uninstall and reinstall driver. Didn't work. So, thinking it might be AVG becaue it puts up a message saying to reinstall. Have clicked where it said, but because I can't get online it couldn't perform the action. I tried downloading the uninstall tool to a flash drive, then onto the computer, but when I attempted to run it, it needed to update, which it can't do because I can't get online!  Is there any way to get the uninstall tool to work without it trying to update online? Any help would be very much appreciated.
