Windows 10: Windows Defender missing

Hi! My windows defender seems to be missing. When I try to search for it, it doesn't show up but the windows defender firewall shows up. It is also gone from the talk bar. When I search Virus & threat protection, the options are grayed out and I'm unable to scan my laptop. Nothing seems wrong with my laptop at the moment except for this. It's also not in msconfig when I look for "Windows Defender Antivirus". It's also missing in HKey_Local_Machine\System\CurrentControlSet\Services. And finally, when I try to use Windows PowerShell and put in Get-Service -Name "WinDefend" Format-Table -Auto, it doesn't work. Please help :

Windows Defender is out

I was working on a computer infested with adware, spyware, and whateverthehellware a while ago. The beta version of Windows Defender found a few things that AVG, Adaware, and Spybot missed.
