DealsFox Virus

What is DealsFox?
Created by DEALSFOX Inc, the DealsFox browser add-on claims to enhance users' Internet browsing experience by enabling comparison shopping and displaying special offers when users visit online shopping websites. While this functionality may seem legitimate, be aware that the DealsFox plug-in is categorized as adware or a potentially unwanted application.
The developers of this browser plugin employ a deceptive software marketing method called 'bundling', thus, most computer users install this browser add-on inadvertently without their consent. After successful infiltration, DealsFox generates intrusive banner, interstitial, full-screen, and text link ads.
Furthermore, this add-on tracks users' Internet browsing activity by recording advertisements viewed, pages browsed, search queries, offers and services of interest to users, browser types, user IP addresses, previous user URLs and time spent at those locations, cookies, and other information.
While this browser extension is not a virus or malware, its presence on your system can lead to malware infections and privacy issues.
Therefore, you are advised to eliminate DealsFox from your Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox). At time of research, this potentially unwanted application was distributed using freeware downloads (via deceptive free software 'download clients') and fake downloads (via fake Java updates, browser updates, etc.)
The DealsFox plug-in is similar to other adware, which infiltrates browsers through free software downloads including, for example, Media Buzz, Rich Media View, and Coupon Downloader.
These browser extensions install on users' Internet browsers when downloading or installing free software, and while they promise to enhance Internet browsing by adding various useful features, in fact, they add no real value. The purpose of these browser plug-ins is to generate revenue from intrusive ads and user tracking.
To avoid installation of such adware, be attentive when downloading and installing freeware. When downloading free software, inspect each step and decline installation of any advertised browser extensions.
When installing downloaded free programs, choose the 'Advanced' or 'Custom' installation options - this will reveal any bundled adware listed for installation. Computer users who observe ads generated by DealsFox should use this removal guide to eliminate adware from their Internet browser/s.
