Remove default-search.net and Linkey project from Firefox, Chrome and IE

Users suffering from repeated redirects to default-search.net due to interference of the Linkey plugin can use this guide to learn how to get rid of the adware.

Adware has been trending in the cybercrime environment for the past few years, partially because it’s a relatively non-aggressive type of malicious software; and also, importantly enough, because it’s inherently associated with Internet advertising which is profitable and allows this corrupt business to flourish. The scheme that will be dissected in this article reflects the accomplice interrelation between a cross-browser plugin called Linkey and a purely malign browser hijacker known as Default-Search. The former entity by Aztec Media Inc. does not appear harmful at first sight – it is a free tool intended for quick and easy access to one’s favorite sites via handy controls. However, some of its installations have a built-in feature that the potential customers are not informed of, namely the forcible toggling of the browsing preferences on the computer.

The settings that get affected by this adware include the homepage, the new tab page URL, and the default search engine. Requiring no authorization whatsoever on the user’s end, it modifies those parameters and assigns them with a new value, that is, default-search.net. That’s the website that will be recurrently showing up as you are surfing the web. The page contains a sponsored ad right on its start screen, and after a query is typed in the search box it comes up with results by a completely different provider, with multiple additional ads embedded. These advertisements are obviously paid for, so Linkey is a goose that lays the golden eggs to its owners’ advantage.

The thing that makes the appearance of default-search.net hijacker on a PC an uninformed decision is the Linkey propagation model assisted by a network of affiliated applications. These apps include some versions of Flash Player and iTunes, the FLV Player tool, and JFileManager. To their credit, these utilities do display a notice on one of the setup screens about authorizing the Linkey plugin to alter the browser configuration. Unfortunately, said information is often disregarded by users or simply stays unnoticed. Overall, the proliferation of this app is very typical for the predominant majority of adware out there.
