Zebar Adware
Written by Tomas Meskauskas on (updated)
What is Zebar?
Developed by SuperWeb LLC, Zebar is a potentially unwanted program (PUP) claiming to improve the Internet browsing experience by enabling coupons, comparison shopping, and other similar functions. While this functionality may seem legitimate and useful, be aware that Zebar is categorized as adware.
These associations are made due to a deceptive software marketing method called 'bundling' (stealth installation of additional programs together with the chosen software) employed by Zebar to install on Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) without users' permission.
After successful infiltration on Internet browsers, Zebar delivers numerous intrusive online ads such as banner, transitional, interstitial, full-page, search, and pop-up ads. There is a high probability that clicking these advertisements will lead to high-risk adware or malware infections.
In addition, Zebar continually tracks users' Internet browsing activity by collecting various software and hardware information including Internet Protocol (IP) addresses, unique identifier numbers, search queries entered into search engines, URLs visited, pages viewed, and other similar information that is likely to be personally identifiable.
This personal information tracking may lead to serious privacy issues or even identity theft. SuperWeb LLC has released over one hundred potentially unwanted programs identical to Zebar. Some examples are Dynamo Combo, DigiHelp, and Boxed Books among many others. These applications (including Zebar) are useless to the user.
The developers of this rogue application release identical PUPs under different names to prevent detection by legitimate anti-spyware and anti-virus programs. The purpose of Zebar is to generate revenue by the display of intrusive online ads and sharing collected data with third parties. Therefore, you are strongly advised to uninstall this rogue application from your system.
Close examination of Zebar reveals that it is mostly distributed via small programs called 'download clients' on freeware download websites such as soft32.com, softonic.com, download.com among many others.
Download clients are used to monetize these websites' free services and traffic by offering installation of advertised (according to the developers, '100% legitimate and virus-free') browser add-ons together with the chosen free software. Thus, reckless download and installation of freeware often results in adware or malware infections, including Zebar.
Installation of Zebar, or other similar adware, can be prevented by paying close attention when downloading free software and never accepting installation of any additional applications offered.
Furthermore, if you are installing downloaded software, select the 'Advanced' or 'Custom' installation options - this will reveal any hidden applications listed for installation and allow you to decline them. If your computer is infected with Zebar, follow the instructions below to uninstall this adware from your Internet browsers.
