    "Cannot open this app" Your IT administrator has disabled windows..."


    Today I recently noticed my windows defender icon has disappeared after I load up into my videogame and didn't see the expected unable to write to documents folder error. I checked to see why and it says windows security is disabled and my edge canary has random polices enabled that I didn't set. I which have removed but I cant enable windows defender again.
    I had tamper protection forced on with a reg key. So I don't see why I got hacked/disabled. Could someone help me remove this malware.

    No the windows security windows just opens like that. The Title box doesn't let me type full error out. But in windows defender app when I click ok button it closes. Here's the log file from Malwarebytes also. I am gonna reboot now to remove some malware.
