“Microsoft Critical Alert” is a cyber threat that belongs to the big group of technical support scams. Numerous malicious websites might deliver this fake security alert. Users might be redirected to such sites when visiting potentially dangerous websites or by a potentially unwanted program (PUP) which sneaked into the computer unnoticed.

The “Microsoft Critical Alert” tech support scam site says “your computer has been infected with a virus and spyware. The following information is being stolen…” and suggests not to ignore the “critical alert” and call a “toll-free” number for help. When infected with such scamware, victim’s web browsers usually start launching phishing pages that are Microsoft Support page look-alikes[1].

However, cybercriminals can be easily recognized. Tech support scammers usually register domains that have anything to do with words “security,” “alert” or “Microsoft.”[2] Besides, the alert is also full of grammar or spelling mistakes. Thus, being vigilant helps not to get tricked by criminals.

The purpose of the “Microsoft Critical Alert” virus is to deceive people into calling tech support scammers[3]. Scammers might convince people into buying and downloading useless or even malicious security programs to delete detected spyware or other malware from the computer. Additionally, the “toll-free” phone number might be just a trick. The phone call might be extremely expensive.

If you ended up on this website once, it might be triggered by some site that forces these redirects. However, if the problem repeats, you should focus on Critical Alert from Microsoft removal which often looks like an adware program.

If one of these seems familiar, you should consider “Microsoft Critical Alert” removal as a matter of utmost importance. If you noticed that your browser unexpectedly causes redirects to shady websites that trigger such fake alerts to you, we highly recommend you to scan the system with Reimage or another anti-malware software to identify and remove “Microsoft Critical Alert” pop-up virus.

Calling the number provided in the fake message will only connect you with tech support scammers that will try to convince you that you need to fix imaginary problems using some rogue security software[4] they will suggest buying. All that scammers want to do is to either rip you off or place malware[5] on your computer.

Sneaky ways how scammers reach their victims

“Microsoft Critical Alert” infection can be distributed via spam, however, in most cases, users install it alongside untrustworthy freeware. Thus, it;s important to chose reliable sources to download software and adjust installation settings in the right way.

Remember that you should always choose Custom or Advanced settings for installing software because they reveal all unexpected additions and allow you to drop them off if needed. Do not believe that “recommended” software installation settings such as Default or Standard are the “right ones” only because the installer suggests choosing them.

However, if you haven’t followed these security tips, you may have unintentionally installed some potentially unwanted programs that spread this nasty scam. Thus, you should find Microsoft critical alert scam removal instructions necessary.
