    Default Windows 10 Home single language doesn't allow any virus guard installations

    Windows 10 doesn't allow installations and block them by the "System administrator has blocked this action. Contact your system administrator or log out and log back in as the system administrator." message.

    When I logged in from the built-in administrator account, it says "The digital certificate of installation files is invalid"

    What do I do to resolve this problem???

    Which security program? Have you downloaded its latest installer from it official website? You should bring this to the notice of the program's developers.

    Also pls see these links:
    Cannot install or uninstall programs in Windows 10/8/7
    Block users from installing or running programs in Windows 10/8/7 >> Reverse the settings and see.
