Where does Zum.com come from?

Research shows that this search page is hosted on IP address, which is located in Yonkers, New York. Our researchers have found that this browser hijacker mostly appears on your computer when you install any software from the ALTools PC utilities (altools.com). These applications are developed by ESTsoft (estsoft.com) and they all seem to be legitimate themselves. As a matter of fact, users tend to overlook the related checkbox that usually offers them an opportunity to opt out of certain browser setting changes during installation. But it is also possible that only the license agreement mentions these changes, which most users do not even read carefully.

In order to promote such a search page to a wider “audience,” it is possible that this hijacker will appear in freeware bundles in the future. As a matter of fact, most browser hijackers use this method to be distributed all over the web. Therefore, it may be vital for you to know that suspicious bundles containing malware infections can be downloaded from questionable websites, including pornographic, torrent, and shareware sites. It is also possible that your computer is infected with adware programs and they generate unsafe third-party advertisements or hijack legitimate advertisements to redirect you to malicious websites or to download infected bundles in the background. If you are in doubt how this browser hijacker has sneaked onto your computer, you should definitely scan your PC with a reliable malware scanner after removing Zum.com.

How does Zum.com work?

Statistics indicate that this browser hijacker is most popular in South Korea (96.1%) and the United States (1.9%). It also seems that this hijacker is increasing in popularity. Although this search page looks totally legitimate at first sight, the truth is, it has no use for you unless you can read Korean. But since there are a number of third-party ads on this page and the search result might also be manipulated to include promoted third parties, we believe that you are better off not engaging with this page at all. Since clicking on potentially unreliable content can result in landing on unsafe websites operated by criminals, you should not keep this browser hijacker in your browser. It is best to remove Zum.com and any other potentially harmful applications and tools that may expose you to unreliable third-party web content.
