Searchqu is an add-on from Bandoo Media, Inc and it gets installed automatically along with iLivid. iLivid is a download manager which gives you the fastest and easiest way to download videos for free. When you install iLivid onto your pc, it offers two basic installations. First one is typical installation, which lists the add-on features such as searchqu toolbar and homepage. Second one is custom installation, which allows you to select the add-ons that you wish to install.
There’s no need to worry if you did the typical installation because this is not a virus or any other type of malicious software. If you have Searchqu on your computer, you should have noticed its toolbar installed and additional search engine called Web Search on your browser. Also it changes your default homepage to www.searchnu.com/406 without user permission.
