How to solve my problem in the eset clean mbr trojan

Hi techy. I download a software eset and I found viruses. But eset still can’t clean or remove the viruses of the hard disk mbr.
So there is a virus in the memory and Eset can’t clean it out. I have tried safe start and then set clean mbr trojan, Malwarebytes . No result at all. What should I do with this problem? TDSS-killer it seems managed to clean it out of the files but my computer is still infected. I can’t disable the eset clean mbr trojan ? please help me to solve this. Thank you.
