How to Remove BackDoor.Generic12.BCNC

[Staxx]

Hi guys! Can someone help me remove a couple of nasty virus. It's called a Trojan Horse.BackDoor.Generic12.BCNC and the other is a Trojan Horse. Dropper. VB.CZE

I have been scanning my PC and keep getting these even if they have already been removed by Malwarebytes.

I think it even downloaded an "anti virus" software by itself called "Security Tools" have any you heard about this before?

Thanks so much!
