These threats install malicious Internet browser extensions and redirect your search results. This means that if you search using Google, Bing, or Yahoo, for example, the site returns normal search results. However, if you click on any of the results, instead of going to the correct website, you might be redirected to a different website.

These threats can also be used for click-fraud.
