CRITICAL ALERT FROM MICROSOFT removal instructions
What is CRITICAL ALERT FROM MICROSOFT?
"CRITICAL ALERT TO MICROSOFT" is a fake error message displayed by a deceptive website to which users are redirected by various potentially unwanted programs (PUPs). Research shows that these programs usually infiltrate systems without consent. In addition to causing redirects, potentially unwanted programs diminish system performance, generate 'malvertising' ads (pop-ups, coupons, banners, etc.), and record various user-system information.
The "CRITICAL ALERT FROM MICROSOFT" error states that the system is infected with the WannaCry virus, your privacy is at risk, and that the malware should be eliminated immediately. You are encouraged to contact "technical support" via a telephone number ("+1-844-301-0371") provided. You are then supposedly guided through the malware removal process. Be aware, however, that "CRITICAL ALERT TO MICROSOFT" is fake and has nothing to do with Microsoft (the Windows Operating System developers). Although the WannaCry virus exists, the error message claims are false - your system is not infected. Cyber criminals generate revenue by scaring and tricking victims into calling and paying for services that are not required. In addition, these people usually demand remote access to users' computers. Once connected, they install viruses and change system settings (for example, user passwords). They offer their assistance in resolving these issues for additional fees. Never call the telephone number. This error can be removed by closing the browser or rebooting the system. Some potentially unwanted programs (and fake error-displaying websites) run background processes (such as mining cryptocurrency). This misuses system resources, thereby diminishing overall performance. Another downside is display of intrusive advertisements. PUPs deliver malicious ads using various tools that enable display of third party graphical content on any site. These ads often conceal underlying content, significantly diminishing the browsing experience. In addition, some malicious ads execute scripts that download and install malware - clicking them risks system infection. Potentially unwanted programs are also known to record user-system information that might contain personal details. This data is sold to third parties, mostly for marketing purposes and to generate revenue. Potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety. Therefore, uninstall them immediately.

There are dozens of fake errors similar to "CRITICAL ALERT FROM MICROSOFT" including, for example, Your Windows Infected With Viruses, YOUR COMPUTER HAS BEEN BLOCKED, and Ransomware Detected. All claims that the system is infected, missing files, or damaged in other similar ways, however, as with "CRITICAL ALERT TO MICROSOFT", these errors are designed only to fool victims into paying for unnecessary technical support. Potentially unwanted programs share many similarities. Most offer 'useful features', however, only a small percentage provide any real value - they are useless for regular users. Their only purpose is to generate revenue for the developers. Rather than enabling the functionality promised, PUPs cause unwanted redirects (thereby promoting malicious websites, most of which are fake search engines), misuse computer resources, deliver malicious ads (via the "Pay Per Click" advertising model), and record user-system information.
How did adware install on my computer?
Research shows that some PUPs have an official download website, however, most are proliferated using a deceptive marketing method called "bundling" together with the aforementioned advertisements. Therefore, PUPs often infiltrate systems without permission or users install them inadvertently, without their consent. Bundling is stealth installation of third party applications together with regular (mostly free) software. Developers hide bundled programs within various sections (usually the "Custom" or "Advanced" settings) of the download/installation processes. Many users rush these processes, skip steps, and click various ads. In doing so, they expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and careless behavior. Therefore, be very cautious when browsing the Internet and especially when downloading/installing software. Malicious ads appear genuine, and thus determining if they originate from the visited (legitimate) website is difficult. They are often distinguishable for their redirects - most lead to survey, adult dating, pornography, gambling, and other similar websites. If you are redirected to such websites, do not click ads and remove all suspicious programs/browser extensions. Note that third party download/installation tools often bundle additional programs. Therefore, never use these tools - download your applications from official/trusted sources only using a direct download link. Furthermore, carefully analyze each step of the download/installation processes and opt-out of all additionally-included programs. The key to computer safety is caution.
