Particle Chrome Extension changes face; Turns into an Adware

Browser Extensions are small programs that add new features to your browser and help personalize your browsing experience.

Such sinister tactics have been going on for years.  Google changed its policy in 2014 so that extensions could only be ‘single purpose’ however, little progress has been made in this regard.

It was noticed, a new code was inserted into the extension that injects adverts in web-sites such as Google, Yahoo, Bing, Amazon, eBay, and
