According to Google, after receiving since January 2015, more than 100,000 complaints from Google Chrome users about unwanted ad injections, the company decided to conduct research regarding ad injections in order to improve its user experience, and improve the web as a whole.

The research is conducted in collaboration with researchers from the University of California, Berkeley, and is based on more than 100 million page views of consumers who are using all the popular operating systems and web browsers.

Although the research is intended to be published on 1 May 2015, Google has already released a briefly worded conclusion in its Online Security blog. According to Google, the researchers have so far found 192 Chrome Ad Extensions which function as ad injectors and violate its policies. AThird of these extensions, according to Google, are classified as "Outright Malware", and due to their considerable effect on millions of users, they have been disabled and removed from the Google Chrome Web Store.

Google expects to use the research to develop and incorporate new techniques to catch new ad injections extensions which violate its policies.
