Some of the free software programs that you install on your computer include third party advertisement offers that you may inadvertently install if you are not careful. When it comes to searchnu.com, that's exactly how the service gets installed on computers in first place.
It is not a virus or malicious in nature, but can nevertheless be frustrating to users who experience the homepage and search changes in their web browser or the toolbar that may get installed as well.
The free download manager Ilivid is one of the free programs that includes the offer to install Searchnu on the computer.
Take a look at one of the installation screens of the program to see how Searchnu is integrated into the installer. Typical installation is selected by default, and since it is quite common for users to simply click next next next in installers to quickly install the program, adware is often overlooked in the process.
If you do not switch to custom installation and uncheck the following two options there before you click on accept and install, you will end up with Searchnu on your computer:
The toolbar will get installed into Internet Explorer and Firefox, the modifications to the homepage and default search engine are being made to Internet Explorer, Firefox and Google Chrome.
Please note that Ilivid is just one program of many that includes the offer to make those changes to your computer. Other names that you may encounter are SearchQu Tolbar, DataMngr, Bando Media, Bandoo.
There are two steps in the removal process.
The first thing that you need to do is close all your open web browser windows, at least those affected by the program, before you uninstall the software from Windows' Control Panel.
The toolbar may have been removed, but you still see the Searchnu.com redirect in your browser, may still use a different search engine than the default, and may still even see the toolbar listed there as well.
If you are using Microsoft's Internet Explorer browser do the following to restore your default settings:
If you are using the Mozilla Firefox web browser do the following to remove the searchnu redirect in the browser.
Google Chrome does not support toolbars, it is therefore only necessary to make changes to the homepage and search provider in the browser.
The following video demonstrates how to remove Searchnu.com/406 from all three affected browsers.
I suggest you download and run a a free antivirus scanner such as Malwarebytes Anti-Malware to make sure your system is clean. Note that the searchnu offering is not considered malware, it is adware.
