Cool Search is a browser hijacker that can change the main settings, like the homepage, new tab address, and search engine. Even though it changes the background of the homepage into a cool interactive animation, there are no other benefits to this application.
It takes over the browsing experience by forcing users to search through a fake search engine that displays the results from Google. The extension can also cause an increased amount of commercial content, like pop-ups, banners, and redirects.
Crooks may use rogue advertising networks that place ads leading to dangerous websites. As a result, people may end up on scam pages that try to lure out personal information, trick them into downloading PUPs (potentially unwanted programs), and even malware.
