As the title says, my windows security app seems to be entirely gone. To my knowledge it is due to malicious software that i have already removed from the computer that might have deleted it. (I also have no third-party antiviruses installed). I have tried manually enabling security services, system health scans, resetting the app completely, editing the registry but nothing worked so far. When I open the app it still greets me as a blank black window and there seems to be no activity from the windows security on my pc in general. It would be great if there was a way to resolve this without complete system reset.
