How to remove malware infected AdSense Ads

Advertisements placed by Google in Web pages are being hijacked by so-called trojan software that replaces the intended text with ads from a different provider.

The trojan redirects queries meant to be sent to Google servers to a rogue server, which displays ads from a third party instead of ads from Google.

The trojan, named after the mythic Trojan Horse because of its ability to enter computer systems undetected, attacks Google's AdSense service, which targets advertisements to match Web page content.

The malware removal process is pretty simple as mentioned below

Simply remove the entries in your hosts file that start contain pagead2 .googlesyndication.com

Just keep the entry for 127.0.0.1 localhost in your hosts file and then you have successfully removed the malware affected AdSense Ads.
