I have a trogan that I can't get to stay removed. Spybot detects it as Zlob.DNSChanger, and Malwarebytes Anti-Malware detects it as Trogan.DNSChanger. Both say they remove it, but then it reappears again rather quickly. My Mozilla homepage gets redirected, and Internet Explorer gets redirected to MSN whenever I try to get to the Windows update site. I've attached the logs from Malwarebytes Anti-Malware, SuperAntiSpyware and hijack this. Can you help me get rid of this thing?
