What is Extreme Blocker?

To many Extreme Blocker is a suspicious program that may have installed without consent. While this is true, this potentially unwanted program (PUP) is cross-browser adware that utilizes very aggressive marketing practices in order to install to a computer system as a browser helper object (BHO), add-on, and extension used to access and gather user information and serve user-targeted advertisements.

Extreme Blocker may be promoted as a free browser add-on and extension used to block advertisements on popular internet browsers, including Google Chrome, Mozilla Firefox, and Microsoft Internet Explorer. However, this program is known to restrict advertisements displayed by competitors in order to generate their own advertisements based off of collected user browser data, such as bookmarks and history.

Furthermore, users who have found this program installed without consent often fall victim to other unwanted programs, malware, and additional malicious traces. If this very probable scenario is the case, a user may experience other activities, such as browser redirects and other programs will need to be eradicated in order to stop unwanted activities from occurring.
