Google has laid out a plan for blocking third-party applications from injecting code into the Chrome browser. The changes will take place in three main phases over the next 14 months. The most impacted are antivirus and other security products that often inject code into user’s local browser process to intercept and scan for malware, phishing pages, and other threats. Google recommends that software vendors update their coding methods and use modern Chrome features such as browser extensions or the Native Messaging API, instead of code injection.
