What is Monsear.xyz?

How does Monsear.xyz work?

Like most other potentially unwanted programs, Monsear.xyz uses the bundling distribution method. The reason the hijacker uses the bundling method to spread online is because it attempts to get installed without the user’s notice. When users install freeware, they rarely pay attention to installation wizard. They skip through it without even realizing that they have just agreed to all additional offers presented in it. Of course, this can be avoided. All you need to do is select the Advanced installation mode and decline all offers of unfamiliar apps that are presented to you.


The main change that you will notice after the hijacker gets installed is that it replaces your home page and default search provider with Monsear.xyz. The page has a search box, the logo of Start4u, and links to popular websites. It may also present you with an added layer of ads. In fact, various advertisements will show up on other websites as well. The hijacker is responsible for these ads, however, it does not endorse them. You click on the ads at your own risk and if you do not wish to expose yourself to various virtual scams, it would be best to stay away from the advertisements. To eliminate them completely, you will have to get rid of Monsear.xyz for good.
