What is ConnectionOptimizer

ConnectionOptimizer is the name of a browser hijacker that infects machines working on macOS. It may be installed on your system as an extension, separate program, or even both after downloading some freeware software. Browser hijackers are software designed to change browser settings to set up fake search engines and spread promotional content. ConnectionOptimizer does exactly the same on various popular browsers like Google Chrome or Safari. The new search engine assigned by it is fake and redirects users through legal Yahoo or Bing. It is also capable of generating additional content like ads to gather clicks and gain some money for the developers. Although ConnectionOptimizer may sound helpful, its functions are totally useless and can be unsafe. Furthermore, browser hijackers tend to have full control of a browser making it difficult to reset the changes via traditional means. You can see the “Managed by your organization” message somewhere in settings meaning your browser is controlled by the unwanted app. Browser hijackers may also have access to reading personal data and stealing sensitive data like passwords or geolocations for revenue goals. ConnectionOptimizer is definitely worth being removed unless you want to face serious threats. Do not worry that much, we will help you do this fast and completely in the instructions below.

How ConnectionOptimizer infected your computer

Unwanted can be delivered via suspicious ads claiming to download fake Adobe Flash Player to fix some “detected” PC problems. In other cases, an app or extension responsible for keeping the hijacker alive on your system could also arrive while installing some other third-party software. Such a technique is more known as “bundling” where unwanted apps get bundled with other free software available on the web. Usually, unwanted apps are offered as something useful in addition to installing the main program. Many users have a chance to avert unwanted infections if being attentive and careful. Alas, most people are not and prone to skip over the whole installation while missing “Advanced/Custom” sections during the process. As a result, this negligent behavior leads to inadvertent installations of adware or browser hijackers we discussed above. In order to not let this happen in the future, it is vital to stay on alert and always be careful while using unofficial installers. Browser hijackers can also be spread via suspicious ads claiming your PC to be outdated or suffering problems.
