No matter what site I go to, I get a "Internet Explorer cannot display the webpage" and it will not open or load. It does the same thing with Norton and Microsofts websites too.

A malware sample that we analyzed earlier -today- pulled a hosts file from txtkxwiicom/ad.jpg. The file contains 200 or so domains that are reconfigured to point to 127.0.0.1 …"
