How the QueryExplorer.com Scam Works

There are plenty of ways in which hackers can take advantage of a browser hijacker in order to make a hefty, albeit illegal, profit. It is important to remember that most online revenue is generated through advertisement impressions and affiliate marketing links. While the vast majority of legitimate companies will earn this revenue by building useful or interesting websites designed to attract Internet traffic, the criminals behind websites like QueryExplorer.com use malware in order to drive up their traffic artificially. Most people visiting QueryExplorer.com do so because they have no choice in the matter. Regardless of their actions, online searches or an address typed into the address bar, will cause the victim's Internet browser to lead him/her to QueryExplorer.com. Any searches performed on this fake search engine will lead to a variety of spam websites that display advertisements, in order to boost the criminals' earnings. The QueryExplorer.com browser hijacker will usually infect a computer through a spam email attachment or directly through an attack website or corrupted Internet advertisement.
