Since sometime I have observed that Google Ads on any website including my blog (http://blogs.digitss.com) gets replaced with something similar to uploaded image below. I am sure it's happening with many people and that could reduce google adsense income.

After some research I found that it is because "yontoo layers runtime" from http://www.yontoo.com/ (tagline says: Platform that allows you to control the websites you visit everyday.) but actually they are taking over. I am not sure with which software they are making a way into users computer but that seems very bad in terms of freedom of Internet and advt/marketing industry. I don't remember I have ever said "yes" to install yontoo on my computer. This piece of software is successful to install itself on my laptop/desktop and workstation at office.

I am going to disable it now but the question is how do I make my websites aware of Yontoo Runtime and stop them from replacing Google Ads?

Basically they are not able to replace all adsense ads but so far they are successfully replaced 1st instance of adsense advt and I am sure in future they will hit more.

There could be 2 approaches 1) Fool yontoo runtime by putting some misleading divs in html document to save actual ads, 2) Completely disable yontoo by working out some client side script (javascript) which can fail/crash yontoo runtime and so will fail it's purpose of replacing ads.

You can visit my blog (http://blogs.digitss.com) and see on top-right corner, if you find that google ad replaced with something similar to image attached with question - it means your computer/browser is infected too.

Looking forward to reply from webmasters, if someone has already wrote some code/plugin to make website (and google ads) safe from yontoo or similar runtime.

FYI: it was able to push this runtime in all browsers installed on machine. So a dangerous threat. And yes, I am just using Google ads - not sure if yontoo runtime is doing trick against other ad networks or not? I am sure they must be doing it with some handful of ad networks.
