Browser Extension removal instructions
What is Browser Extension?
Intrusive online advertisements, 'Ad by Browser Extension', are delivered by potentially unwanted programs and browser extensions that employ a deceptive software marketing method called 'bundling' to infiltrate Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox). This marketing method allows developers to distribute their software together with other programs, and for this reason, most infections are caused by reckless download and installation of freeware downloads. Ads by Browser Extensions redirect users to the Advertising Support website. The types advertisements delivered include banner, coupon, and pop-up ads. Clicking advertisements generated by rogue browser plug-ins (such as 'Ad by Browser Extension') may lead to further adware or malware infections.
Most popular freeware download websites including download.com, soft32.com, and softonic.com, use bundling to monetize their free services and traffic. Although these websites claim that download managers promote '100% legitimate and virus-free' applications, reckless download and installation of freeware often leads to high-risk adware or malware infections. To prevent installation of adware that causes 'Ad by Browser Extension' advertisements, closely inspect each step of the free software download procedure and uncheck all additional applications (for example: add-ons, toolbars, browser setting modifications, etc.) listed for installation. In addition, select the 'Custom' or 'Advanced' options when installing downloaded software - this will reveal any bundled applications listed for installation and allow you to decline them. You are strongly advised to follow the removal guide provided to uninstall all suspicious plug-ins from your Internet browsers.
Rogue browser add-ons that generate 'Ad by Browser Extension' advertisements are similar to other adware-type applications. These provide no useful features and deliver intrusive online ads. Some examples are WebBrowser, I-Cinema, SlimPrice, deals, and many others. Intrusive online advertisements employed by these potentially unwanted programs are displayed on websites visited and are bundled with third-party browser plug-ins. Installation of browser extensions causing 'Ad by Browser Extensions' can be prevented by paying close attention to each step of the free software download and installation process. To eliminate these annoying advertisements, study the extension list within your Internet browser settings and uninstall all suspicious recently-installed browser add-ons.
