To obtain user information, Qvo6 most likely utilizes several different tracking technologies on the affected computer. A good example would be the cookies we examined, connected with its own and another suspicious domain, going by the name These type of cookies are most likely connected with the advertisements displayed on the web page of the search engine.


More to it than that, Qvo6 has an ad-supported ‘Games’ section that redirected us to a website, called It featured various familiar and unfamiliar games, like Plants and Zombies, for example. When clicked on, it immediately redirected to a download page that prompted the download of a toolbar, called Gaming Wonderland.


This toolbar is distributed by the infamous Mindspark Interactive Network Inc. (one of those suspicious third-parties mentioned earlier). This organization aims solely to do one thing – create toolbars and extensions that are ad-supported to generate profit . They are often regarded as potentially unwanted programs and detected as such by some anti-malware programs. And more so, Mindspark has regarded their own products as unsafe in the ‘7.Security’ paragraph of their EULA agreement.

Also, when you look up Qvo6 in detail, you will eventually establish that the connection of the user with this web page is not encrypted. Non-encrypted connections are prone to all HTTP-based attacks, including phishing to steal user data.


This lack of security is not essential for any legitimate search engine, and it is strongly advisable to remove immediately it from the computer.

So, the bottom line is that this suspicious search engine is most likely set by a browser hijacker on your computer with one purpose –to make money to its developers. Both cyber-criminals and professional security engineers have realized that the method of infection is more important than the threat itself. This makes it the bottleneck of the whole malware infection process. This is why the unwanted apps may display pop-ups on your computer, show ad-supported search results and probably even replace the web locations when you click on the legitimate search results. Since most cyber-scammers work with third-party sites, they do not mind what sites they advertise. This is why it is recommended to remove everything associated with this unwanted code on your machine. Also, you may not be able to remove it completely and your antivirus may not identify it since it is considered a low-level threat. This is why any anti-malware program, focused on removing PUPs from computers should be able to do a successful removal.
