The main thing to remember when it comes to browser-hijacker distribution is that these apps don’t typically come as separate programs and are instead bundled with some other software that users are more likely to want in their systems. In other words, the majority of browser hijacker apps are distributed through the file-bundling technique. They get added as a bonus feature to the installer of another app or program and if the user doesn’t manually uncheck them while customizing the setup settings, they get installed on the computer. And while unchecking the hijacker from the setup menu usually requires no more than two or three clicks, most users don’t bother to do that, which is what gets them unwanted apps like MainWindow, Altruistics, Grand Explorer and Sensiblemoth.
