Hi, My name is John, and I'm a member of the Searchqu Support Team. I'm here to help :) When iLivid installs onto your pc it offered two basic installs, typical installation, which lists the add-on features such as searchqu default search engine, and 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 install - this isn't a virus, nor malware, and there's no need to Perform a virus scan against it. In order to change searchqu as a default search engine please check: http://bit.ly/searchqutoolbar , it will give you the instructions how to do it.

we are here to assist with any further question :)

The searchqu support team.
