Windows Defender does not remove malwares

[Lurker22]

Hello, I am using Windows 8.1.

Every time I scan my laptop, Windows Defender detects these malwares :


Trojan:Win32/Occamy.C48


VirTool:Win32/Obfuscator.C


Trojan:Win32/Malex.gen!E


Trojan:Win32/BlueTeal!rfn


All of them show as severe active threats.


When I quarantine or remove them, Windows Defender appears to remove them and shows my PC status as safe. But, when I scan again, the same four files reappear.

Please help.
