200 Chrome Ad Injectors are removed by Google

Moe than 5 percent of all visitors to Google's Web sites have at least one ad injector knowingly or unknowingly installed on their operating systems. Google is aiming to rid its Chrome Internet browser from ad injectors after it found that almost 200 ad injectors exposed millions of users of the browser to malicious software.


Ad injectors are programs that insert new ads, or replace existing ones, into the pages you visit while browsing the web. Google received more than 100,000 complaints from Chrome users about ad injection since the beginning of 2015—more than network errors, performance problems, or any other issue. 
Injectors are yet another symptom of “unwanted software”—programs that are deceptive, difficult to remove, secretly bundled with other downloads, and have other bad qualities.

Unwanted ad injectors aren’t part of a healthy ads ecosystem. They’re part of an environment where bad practices hurt users, advertisers, and publishers alike. 

People don’t like ad injectors for several reasons: not only are they intrusive, but people are often tricked into installing ad injectors in the first place, via deceptive advertising, or software “bundles.” Ad injection can also be a security risk, as the recent “Superfish” incident showed. 

But, ad injectors are problematic for advertisers and publishers as well. Advertisers often don’t know their ads are being injected, which means they don’t have any idea where their ads are running. 

Publishers, meanwhile, aren’t being compensated for these ads, and more importantly, they unknowingly may be putting their visitors in harm’s way, via spam or malware in the injected ads. 

In Chrome, any extension hosted in the Chrome Web Store must comply with the Developer Program Policies. These require that extensions have a narrow and easy-to-understand purpose.

Researchers at University of California Berkeley, drew conclusions from more than 100 million pageviews of Google sites across Chrome, Firefox, and Internet Explorer on various operating systems, globally. It’s not a pretty picture. Here’s a sample of the findings:

  • Ad injectors were detected on all operating systems (Mac and Windows), and web browsers (Chrome, Firefox, IE) that were included in our test.
  • More than 5% of people visiting Google sites have at least one ad injector installed. Within that group, half have at least two injectors installed and nearly one-third have at least four installed.
  • Thirty-four percent of Chrome extensions injecting ads were classified as outright malware.
  • Researchers found 192 deceptive Chrome extensions that affected 14 million users; these have since been disabled. Google now incorporates the techniques researchers used to catch these extensions to scan all new and updated extensions.
