XFinity Toolbar is a program created by Comcast and when installed, it changes the default homepage and search settings to "http://xfinity.comcast.net " in popular Web browsers, such as Internet Explorer, Google Chrome or Mozilla Firefox, without the user's permission. In fact, XFinity Toolbar modifies the browser settings in order to perform browsing redirects into advertisements and earn money from their publishers.
XFinity Toolbar is designed to modify your browser settings and may install additional plugins (toolbars, extensions or add-ons) in your Web browser in order to promote other links or products. Browser hijackers like this, may redirect the user's computer into malicious websites or may install malicious programs in order to compromise the user's computer to security risks.
Technically "XFinity Toolbar" is not a virus and is categorized as a malware program ("Potentially Unwanted Program (PUP)" that may contain and install malicious programs on your computer, like adware, toolbars or viruses. If a computer is infected with "xfinity.comcast.net" hijacker, then more pop-up ads, banners and sponsored links are displayed on the victim's computer screen or inside the Internet browser and in some cases the computer speed may be slowed down due to malicious programs running on the background.
XFinity Toolbar hijacker program was probably installed without the user's notice because it is commonly bundled inside other freeware software which are downloaded -and installed- from known internet sites like "download.com (CNET)", "Softonic.com", etc. For that reason, you must always pay attention at the installations options for any program you install on your computer, because most software installers contain additional software that you never wanted to install. In simple words, DO NOT INSTALL ANY IRRELEVANT SOFTWARE that comes with the software installer of the program that you want to install. More specifically, when you install a program on your computer:
- DO NOT PRESS the "Next" button too fast at the installation screens.
- READ & ACCEPT CAREFULLY the Terms and Agreements.
- ALWAYS SELECT: "Custom" installation.
- DECLINE to install any offered additional software that you don't want to install.
- UNCHECK any option that says that your homepage and search settings will be modified.
