Qualitink Virus

What is qualitink?

Developed by SuperWeb LLC, Qualitink is a potentially unwanted browser extension claiming to enhance users' Internet browsing experience by enabling coupons, comparison shopping, and adding other useful functionality. Although Qualitink may seem a legitimate browser plug-in, be aware that it is categorized as adware.

Qualitink deploys a deceptive software marketing method called 'bundling' to install on Internet browsers (Internet Explorer, Mozilla Firefox, and Google Chrome) without users' consent.

Following successful infiltration, this extension generates various intrusive online advertisements including banner, interstitial, transitional, text-link, search, and full-page ads. There is a high probability that clicking these advertisements will cause additional adware or even malware infections.

Furthermore, this potentially unwanted application continually monitors users' Internet browsing activity by recording various software and hardware information such as search queries entered, URLs visited, pages viewed, unique identifier numbers, IP addresses, and other similar details.

Be aware that this recorded information may be personally identifiable and such behavior may lead to serious privacy issues or identity theft. SuperWeb LLC has released over one hundred rogue browser extensions identical to Qualitink. Examples include ProductivityPro, Loffinam, and Webget.

The company releases identical browser plug-ins under different names to avoid detection by legitimate anti-virus and anti-spyware software.

These add-ons claim to improve users' Internet browsing experience in some way, however, neither Qualitink, nor any of these other plug-ins add any read value for the user. Their purpose is to generate revenue by the display of intrusive online advertisements.

Most potentially unwanted applications are distributed via small programs called 'download clients' within freeware download websites (such as, for example, download.com, softonic.com, and soft32.com). Download clients are used to monetize the websites' free services by offering installation of additional browser extensions along with the chosen free software.

In most cases, reckless download and installation of freeware results in adware or malware infections. This situation can be prevented by closely inspecting each step of the free software download process and never accepting installation of any additional applications offered.

Users who install downloaded freeware should choose the 'Custom' or 'Advanced' installation options, rather than 'Quick' or 'Regular' - this will reveal any bundled applications and allow removal of them from the installation list.

If you have installed Qualitink and observe "Ads by Qualitink", "Powered by Qualitink", and "Qualitink Deals" advertisements when surfing the Internet, follow this removal guide to eliminate Qualitink adware from your Internet browsers.
