Backdoor.bot Won't delete

[Imran619]

I have found Trojans on my Malwarebytes which won't delete. I would delete them then restart the computer and scan with Malwarebytes and get more or maybe the same amount of Trojans. I did use AVG that managed to reduce the Trojans but getting rid of 6 of them but it can't find the other Troans. Here is my Malwarebytes log,

After deleting all these they will come back again =/

Is there any solution to this?
Thanks
