Some time ago i opened a thread regarding an infection found using Malwarebytes called "Trojan.DNSChanger". I thought the computer was clean after following the steps provided but now Malwarebytes found again the same infection.

This is the log:

Removing the infection using Malwarebytes does absolutely nothing, on the next restart the virus is still there.
Please help.

The problem might be the router. That could explain why i got malware on a newly formatted hard drive before i even download anything at all. Same thing on the other notebook i own: recently formatted hard drive with only software downloaded from trusted sites (like the antivirus etc.), infected with malware out of nowhere.


I don't know what to do, how do i know for certain if my router has been compromised?
