Welcome, reader, to our “Microsoft Critical Alert” Pop-up Scam removal guide. The following instructions will aid you in removing the unwanted software from your PC.

You have come to the right page if you would like to learn how to effectively remove the annoyance that “Microsoft Critical Alert” is probably causing you. This program is a browser hijacker and what it typically does is, it replaces the homepage and the default search engine of your browser (be it Chrome, Firefox, IE, etc.) and redirects you to various sponsored advertisement pages full of annoying ads, pop-ups banners, and links. Fortunately, this is nothing permanent or dangerous and in the guide below we will show you how to remove the annoying program and all of its changes. But even though “Microsoft Critical Alert” cannot be considered as dangerous as a computer virus, it still needs a bit of understanding before you proceed to the removal instructions. That’s why we suggest you read the information below to familiarize yourself with the specifics of this software.

Can “Microsoft Critical Alert” be compared to a virus?

If your browser has suddenly been invaded by an intrusive program that imposes some changes on it, and the ads and popping tabs seem impossible to be stopped, the first thing you may think of is a virus or some nasty malware like a Trojan or Ransomware. However, “Microsoft Critical Alert” is not a virus and it falls under a different category of software called Browser hijacker, which is not a harmful, but rather unwanted type of software. Generally, browser hijackers are browser components, which aim to expose you to online advertisements, and they do that by imposing some changes in your browser and redirecting your web searches to all kinds of sponsored advertisements. The online advertising industry is using such applications to directly display advertisements on the user’s screen while they are browsing the web. Very often, advertisers pay programmers huge amounts of money to bring traffic and clicks to their websites, and browser hijackers are used exactly for that purpose. The infamous Pay-Per-Click method comes into play here, where the hijacker developers receive some money from every click that redirects users to such sponsored ads, pop-ups, banners and pages. In recent years, this method has turned into a popular source of income for many online based businesses and software developers. Since profits here can be huge, so is the amount of the intrusive browser hijackers that may interrupt your browsing activity.

Users usually install the browser hijacker by themselves

In case you’re wondering how “Microsoft Critical Alert” got installed on your computer and took over your browser, you should know that you may have installed it there yourself. This usually happens thanks to a distribution method called software bundling where ad-generating components like browser hijackers may get bundled inside the installer of another program that the users download and install. Free software may contain such a bundle, but you may also get it if you download applications from file sharing platforms, torrents, free installation managers, spam email links, open source download platforms or even free downloads from the web. The moment you run the setup, it may prompt you to the standard installation procedure, and this is what most users do. However, in order to prevent any additional software from getting installed along with the software you desire, it is best to skip that option and seek for the so-called Advanced or Custom installation. Not only it will reveal the bundled programs if any, but it will enable you to prevent their installation. Do keep in mind that preventing them is way easier than uninstalling them later, and in most of the cases, you may need a removal guide like the one below to fully remove the browser hijacker.

Uninstalling “Microsoft Critical Alert” may save you from some hidden hazards…

Even though “Microsoft Critical Alert” is not malicious itself, you should always keep in mind that tricky threats such as viruses, Trojans and even the recently popular Ransomware may hide in many different places and may use different system vulnerabilities to sneak inside your PC. Randomly popping ads, page redirects, and intrusive messages are some of the favorite places, where hackers love to hide their malware. That’s why, it is not excluded that, in the flow of advertisements, you may unknowingly come across a real nasty infection. Having this in mind, it may be best to uninstall “Microsoft Critical Alert” in order to eliminate the possibility of unexpected security hazards. Moreover, the irritation and the browsing-related disturbance this browser hijacker may cause can really drive you nuts. Your browser may become so slow, due to the unstoppable flow of ads that it tries to display, that it may take ages for you to load the pages you want. Your computer may also get sluggish and no one likes a sluggish system. In case that this is enough for you to decide to remove “Microsoft Critical Alert”, the guide below contains all the needed instructions.
