You appear to be affected by DNSChanger
If you see this article’s title as the answer when you navigate to following URLs or they show red then let me tell you that you are affected by a malware that will not allow you to access internet after 9th July 2012.
Check your system first:
DNSChanger is a class of malicious software (malware) that changes a user’s Domain Name System (DNS) settings, enabling criminals to direct unsuspecting internet users to fraudulent websites and otherwise interfere with access to internet services. It has been associated with ‘click fraud’, the installation of additional malware and other malicious activities.
Nearly 3 lakh DNSChanger virus-hit computers, including over 20,000 in India, may lose Internet access from Monday, July 9.p
