What is System Notifier?

System Notifier is a browser plug-in that we recommend removing. Don’t worry – it’s not a serious computer infection. However, it is capable of hijacking web browsers (Google Chrome, Mozilla Firefox, Internet Explorer) and causing them to work slower than it used to. By the way, it may be set to display commercial advertisements and collect information about your browsing habits. Therefore, it goes without saying that System Notifier is an adware or a potentially unwanted program (PUP) that is not recommended keeping. Most of the users have been tricked into installing it believing that it will notify them about suspicious programs on their computer. However, instead of promised alerts, System Notifier virus may start initiating commercial advertisements (pop-ups, pop-unders, banners, in-text link, full-page ads). They may be filled with various deals, offers, discounts, promo codes and similar things. Despite their appealing and trustworthy look, ‘Ads by System Notifier’ should not be trusted because they may redirect you to questionable or even unsafe websites. Even more, you may receive fake update alerts brought by System-notifier.com domain. These ads may offer you to update Java, Flash Player, Media Player or another popular software or may inform you about issues on your computer and offer to call for remote tech support. Be careful and do not fall for that because System Notifier pop-up ads may trick you into installing other potentially unwanted programs, such as Hit the Lights, Go HD, ZoomIt, MetaSearch, or you may subscribe suspicious service unconsciously and may receive an increased telephone bill. Fortunately, you can stop suspicious ads from appearing. For that, we recommend installing Reimage and remove System Notifier virus with its help.

How can System Notifier hijack my computer?

We haven’t found any download websites where System Notifier virus would be promoted on its own. Therefore, it’s obvious that its users installed it bundled with other freewares and sharewares. Probably you are already aware of ‘bundling’ distribution method. However, we will shortly remind you that ‘bundling’ enables freeware developers to monetize their products by filling them with third-party apps, such as browser add-ons, plug-ins, toolbars, and extensions. Unfortunately, ‘optional components’ usually appear to be adwares or browser hijackers that once installed cause various inconveniences during browsing. If you want to prevent installing ‘optional downloads’, first of all you should avoid third-party installers, such as Installrex, Vittalia, Amonetize, Softonic, Soft32, etc. because they are most commonly bundled with freewares. Besides, you should always select Advanced or Custom installation option and uncheck ticks claiming that you agree to install optional downloads. Otherwise, you may start experiencing System Notifier redirects to questionable websites and may be tricked into installing other potentially unwanted programs. If you are going thru this experience right now, you should not waste your time anymore and get rid of suspicious adwares right away.

How to remove System Notifier virus?
