What is CommonShare?
CommonShare is a potentially unwanted browser extension claiming to enhance users' Internet browsing experience by enabling coupons, comparison shopping, and displaying website trust ratings. It is developed by SuperWeb LLC and compatible with Internet Explorer, Google Chrome, and Mozilla Firefox.
Although this functionality may seem legitimate, users should be aware that the CommonShare add-on is categorized as adware.
This potentially unwanted application installs on browsers without users' permission using a deceptive software marketing method called 'bundling'. After successful infiltration, this extension generates various intrusive advertisements, including interstitial, transitional, search, banner, text link, and full page ads.
Furthermore, the CommonShare plugin tracks users' Internet browsing activity by recording search queries, URLs visited, pages viewed, browser information, IP addresses, unique identifier numbers, and other information. The presence of adware such as CommonShare on your system may lead to serious privacy issues, identity theft, or malware infections.
CommonShare is identical to other rogue browser plugins released by SuperWeb LLC including Fralimbo, Findopolis, or BrowseDen.
This company creates identical browser plugins under different names to avoid detection by antivirus and anti-spyware programs. CommonShare is not a legitimate browser add-on - its main purpose is to generate revenue from displaying deceptive online advertisements.
Computer users should be aware that, today, most current freeware download websites (including, for example, download.com and soft32.com) use 'download clients' to monetize their free services. Therefore, Internet users should express caution while downloading and installing free software.
Download clients are small programs offering installation of advertised browser plug-ins together with the chosen freeware. By not paying close enough attention when downloading and installing free programs, you may inadvertently install various unwanted advertisements-generating browser add-ons.
To avoid installation of CommonShare or any other potentially unwanted applications, closely inspect each freeware download step and decline installation of promoted browser plug-ins.
When installing freeware, choose the 'Advanced' or 'Custom' installation options, rather than 'Quick' or 'Typical' - in this way, you will be able to decline installation of any bundled browser extensions.
Internet users who observe 'Ads by CommonShare', 'Powered by CommonShare', and 'CommonShare Deals' when browsing the Internet, should use this removal guide to eliminate adware from their Internet browser/s.
