qvo6-virusA browser hijacker, related to the suspicious Qvo6.com web page that uses redirects to Google results and employs cookies to track user information has been reported to be detected on over 600,000 PCs for the last two months. This potentially unwanted program is very dangerous to the user, and it exhibits a rather suspicious behavior. This may involve cookies that track various different user activities, random browser redirects, and advertised content in the form of ad-supported search results, black SEO, pop-ups, highlighted text and others that all lead to third-party websites of unknown origin. Security investigators report it to change the homepage and the new tab page of the browser it has been installed on to qvo6.com.

Qvo6.com Browser Hijacker – How Did I Get It?

The most effective method of distribution such applications use is software bundling. It means adding the browser hijacker to the installer of a free program. Third-party websites that support the download of different free programs in one place use this strategy in order to push their products into the market. If you have downloaded your favorite media player, photo maker, video converter, downloader, etc. there is a good chance such program may have been bundled and mentioned in the EULA agreement. It should be checked every time prone to installation. This is an annoying process, and this is why it is good to use EULAlyzer (http://www.brightfort.com/eulalyzer.html).

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 odin.goo.mx. 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 gaggame.com. 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.

gaming-wonderland-toolbar

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.
