  • Hi,

     

    According your description, I suspect that some Windows Firewall related modules are corrupted in your machine. Please try to use “SFC /scannow”  to check the system file.

     

    1.       Run cmd.exe as administrator.

    2.       Type “sfc /scannow” in prompt window, press Enter.

    3.       Check the result.

     

    If the issue persists,  you could perform an In-Place Upgrade to repair your Windows 7:
