What is System Notifier?

System Notifier is a potentially unwanted program (PUP) that claims to notify users whenever there is a system-related program/update available. This may seem legitimate and useful functionality, however, be aware that System Notifier is categorized as adware. These associations are made due to a deceptive software marketing method called 'bundling' employed by the developers of this rogue add-on to install on Internet browsers without users' consent. Bundling allows the developers to distribute their applications together with other software, and therefore, most users inadvertently install System Notifier together with free software downloaded from freeware download websites. After successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, System Notifier generates various intrusive online advertisements and monitors users' Internet browsing activity.

Advertisement types delivered by System Notifier are most commonly banners, pop-ups, coupons, and in-text ads. Be aware that clicking these advertisements may result in further computer infections. Tracked information (information IP addresses, website URLs, pages viewed, search queries, etc.) may be personally identifiable and can lead to serious privacy issues or identity theft. There are many applications similar to System Notifier. For example: PaceItUp, IntelliTerm, AllCheapPrice, and SaveLots. These applications are just some examples among hundreds of others, none of which are useful to the user - they are developed to generate revenue by the display of intrusive online advertisements and by sharing collected data with third parties. For these reasons, you are strongly advised to eliminate System Notifier from your Internet browsers.

Research shows that most adware is distributed via small download programs such as download managers (called 'download clients', 'installers', etc.) used by freeware download websites including download.com, softonic.com, soft32.com, etc. Download managers are used to monetize these websites' free services and traffic by offering installation of promoted (according to the developers, '100% legitimate and virus-free') browser add-ons together with the chosen free software. Thus, careless download and installation often results in adware or malware infections. To prevent this situation, closely inspect each step of the free software download procedure and click 'Decline' against any offers of additional software installation. Furthermore, when installing downloaded programs, select the 'Advanced' or 'Custom' installation options, rather than 'Quick' or 'Typical' - this will reveal any bundled applications listed for installation and allow you to decline them. If your system is infected with System Notifier, follow the instructions below to eliminate this adware from your computer.
