Z-Quest is adware that adds advertisements on the top and bottom of web pages viewed with Internet Explorer. It is installed by trojans, without the user's knowledge or consent. There is no visual indication the adware is running on the system other than the additional advertisement banners.

Z-Quest adds banners to the top and bottom of some web pages viewed with Internet Explorer. The banners can be very difficult to distinguish from banners designed to be on the web page.


Example with Z-Quest banner




Original




Z-Quest has a set of banners to display from which it randomly selects. Some of the advertisements contain code to generate pop-ups.

Z-Quest can be installed silently by trojans. There is nothing to indicate that Z-Quest is running on a user's computer.
