Usually, users download bundled installers from untrustworthy file-sharing websites. Such sites could distribute bundled installers to promote unwanted software. Since many users do not review or simply do not notice any suggestions on the setup wizard, they end up installing unwanted programs. That usually happens when instead of choosing the advanced installation settings, users allow applications to be installed automatically.

The browser hijacker changes default homepages by modifying particular files and Windows Registry entries. For instance, in order to set as a homepage on Internet Explorer, the application replaces value data or the Start Page, which is located in the HKCU\Software\Microsoft\Internet Explorer\Main directory. However, the Mozilla Firefox browser is slightly different in this matter as it saves user preferences in the prefs.js file. For example, if you open prefs.js file as a Notepad document you can find a particular line that commands the Mozilla Firefox to open any web page that is chosen as the homepage. It is very similar to the Google Chrome browser, just instead of the pref.js file, it has three documents called Preferences, Secure Preferences, and Web Data. Thus, if you noticed on Google Chrome or Mozilla Firefox, it means that the browser hijacker modified the mentioned files.

For example, the third-party site could try to collect your personal data, such as email address, telephone number, etc. Often this type of information is asked in exchange for various freebies, coupons, free trials, and so on. Therefore, you have to be very careful once you land on a suspicious site. If you think that something is wrong with it, you should leave the web page immediately, because some of the sites could be created to spread malware as well. Because of these risks, we advise you to replace with a reliable search engine that does not modify search results.
