  • Question

  • After a nasty virus was taken off my computer, my Windows Firewall seems to be missing.  How do I go about having it reinstalled?

  • 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:
