In most of the cases, users don’t really know how exactly the Browser hijacker has gotten installed on their computer. The reason for that is that usually, this type of software becomes part of the system along with some other programs which the user downloads from the Internet. Normally, the most common carriers of annoying ad-generating and page-redirecting programs are different torrents, spam email messages, email attachments, free download links, ads and free software bundles. What typically happens when the users come across such free sources of software is that they don’t pay much attention the additional and free components in the downloaded software package which might be bundled with the main program. This is how they end up with different potentially unwanted apps such as browser hijackers, adware and in some cases even nasty viruses – Ransomware, Trojans and others.
