WebQuestSearch is a Mac application that acts as a browser hijacker due to its ability to take over certain browser settings while preventing users from changing them back to their original state. Furthermore, WebQuestSearch also has been observed to possess adware capabilities such as delivering unwanted advertisements that could be delivered as pop-up windows or possibly injected into the search results of any conducted search query. Applications similar to WebQuestSearch often resort to utilizing dubious distribution methods such as 'bundling' or even pretending to be updates or installation files for legitimate software programs. As a result, these applications also are considered to be Potentially Unwanted Programs (PUPs).
No matter how WebQuestSearch has managed to install itself onto the user's computer, it will proceed to modify the homepage, new page tab, and the default search engine to open a fake search engine. The consequence is that every time the browser is opened, it will have already generated traffic towards the promoted engine. However, for the actual search results, it is relied upon one of the mainstream search engines such as search.yahoo.com or Google Custom Search.
Keeping WebQuestSearch, or any similar browser hijacker application comes will several serious caveats. Users should not forget that, in most cases, these applications will monitor and log various browser data - visited sites, clicked URLs, and every search query that has been initiated from the affected browser. The device's IP address and the geolocation also could be tracked.
