Could someone please help me out with this:

My DNS Server is supposed to be assigned automatically...but because of this trojan its always getting an address like 85.255.112.219;85.255.112.220...
As a result I cant connect to the internet (which i do using a VPN connection)

I detected the DNSChanger Trojan, i can see the invalid registry enteries, i deleted them manually. Then through MalwareBytes. They were deleted but were back the next instant.... That is the problem, it just keeps on coming back....

here is my HijackThis Log:
