Hello, I have a PC on my network that is having odd problems. It cannot resolve any external DNS. I can ping any address by IP, but cannot ping by DNS nor can I browse to the website (obviously). I have tried manually changing the DNS the PC uses and have also flushed the DNS on the laptop to no avail. I have ran malewarebytes, and it found 4 infections which I cleaned but it still isn't working correctly.

Has anyone ran into a virus like this?
