The problem is actually based in your router.

tab, select Check for Updates
Next disconnect your system from the internet, and your router, then…
Open MBAM in normal mode and click Scanner
scan and scan (normal mode).
After scan click Remove Selected
Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you dont know the router's default password, you can look it up HERE
However, if there are other infected machines using the same router, they will need to be cleared with the above steps before resetting the router. Otherwise, the malware will simply go back and change the router's DNS settings. You also need to reconfigure any security settings you had in place prior to the reset. Check out this site here
for video tutorials on how to properly configure your router's encryption and security settings. You may also need to consult with your Internet service provider to find out which DNS servers your network should be using.
Once you have ran Malwarebytes' Anti-Malware on the infected system, and reset the router to its default configuration you can reconnect to the internet, and router. Then return to this site to post your logs
