What is Security Utility?

Created by Security Utility 1 Ltd, the Security Utility add-on claims to help users find and compare the best prices for products while shopping online. Security Utility is compatible with Internet Explorer, Google Chrome, and Mozilla Firefox. While this added functionality may seem legitimate, many Internet users refer to Security Utility as a virus or malware. These negative associations are made since this plug-in is distributed using a deceptive software marketing method called 'bundling' - the add-on installs on browsers together with free software downloaded from the Internet. Furthermore, Security Utility generates various banner, search, in-text, and pop-up ads when surfing the Internet.

security utility adware

This behavior is typical of adware or potentially unwanted programs (PUPs). Although this browser add-on is not a virus or malware, be aware that clicking advertisements generated by Security Utility may lead to serious computer security and privacy issues. A clear indication that your Internet browsers are infiltrated by this potentially unwanted application are "Powered by Security Utility", "Security Utility Advertisement", and "Ads by Security Utility" advertisements generated while surfing the Internet. You are strongly advised to remove this adware from your Internet browsers.

This adware is similar to other PUPs, which install without users' consent together with free software downloaded from the Internet. Examples include TheAnswerFinder, iToolBox, Meteoroids, and GeniusBox among many others. These browser add-ons provide no significant value and cause various unwanted ads that may lead to installation of malware or additional PUPs. The best way to avoid installation of adware is to be attentive when downloading free software. If your download is managed by a 'download client', opt-out of installation of any promoted browser plug-ins by clicking the 'decline' button. When installing free software, choose the 'Advanced' or 'Custom' installation options, rather than 'Typical' or 'Quick'. This will reveal any bundled browser extensions listed for installation and allow you to opt-out. If you observe advertisements caused by Security Utility, use the removal guide provided to eliminate this potentially unwanted application from your Internet browser/s.
