Common Browser

Common Browser is an ad-producing software app that gets attached to Mac browsers and hijacks their homepages and search engines. Once Common Browser becomes a part of the browser, it then proceeds to spam it with aggressive page redirects and site-promoting popups and banners.

The only way to end this is to fully uninstall this unwanted app from your Mac. Removing this browser-hijacking software is indeed what you should do if it is currently in your system. The presence of Common Browser in your browser can not only be quite frustrating but it could also potentially make your Mac more exposed to various external threats, including phishing sites, Trojan horses, spyware viruses, Ransomware, and other dangerous threats. If you need any help removing this browser-hijacking app from your Safari, Firefox, or Chrome browser, be sure to check out the instructions you will find at the end of this post.

Common Browser for Mac

Common Browser for Mac is a recently reported browser hijacker app that can take over any Mac browser and turn it into an advertising tool. Common Browser for Mac will constantly try to popularize certain sites by redirecting users to them, thus artificially boosting their traffic.

Even though it is not uncommon for both regular users and security researchers to define apps like this one and Gsearch as viruses, it must be said that the actual goal of most browser hijackers isn’t malicious. Advertising certain sites and the products they offer is, in and of itself, not a harmful goal. It’s the way that browser hijackers typically try to achieve their goal that could be potentially harmful.

The first issue here is that there’s typically not a whole lot of control imposed over the content that these apps are tasked with promoting. Needless to say, this means that many of the sites that get popularized by browser hijackers may actually be hazardous to the end-users and even potentially expose them to virus programs, Ransomware, Trojans, and other dangerous external threats.

In addition, users are rarely given the option to, by the very least, limit the ad generation conducted by these unwanted apps. Thirdly, it should also be said that most hijacker tools don’t even offer users anything useful, which is yet another reason why the best course of action would be to have the hijacker uninstalled.
