Technical Details

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

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.
