“CRITICAL ALERT FROM WINDOWS” is a tech support scam that locks you out of the computer and says that it has been blocked to prevent further damage. You’re also informed about a security breach of your network, and told to call one of the two provided numbers – either +1-844-350-3335 or +1-844-363-5003. You’re promised help from qualified engineers once you do so, but we’re here to tell you that you shouldn’t do so no matter how desperate the situation seems. Even though you’re told that the number is toll-free, it’s actually not in reality, and the amount of money that has to be paid for calling it is significant.
More than that, you will be told many things by people on the other side of the line, but they won’t tell you about the source of the problem. We, on the other hand, will – “CRITICAL ALERT FROM WINDOWS” is caused by a Trojan. Removing it is enough to return the computer to normal, but its creators, of course, don’t want this happen. They’re interested in getting as much money from you as they can, so they will try to keep you on the line for a very long time. But you now know that you don’t have to call this number, and that your network isn’t breached. So the removal of this threat should become your next step.
Download a program such as SpyHunter and use it to achieve this goal. You may run into some problems, but fear not – our site has a manual that can get you out of any trouble. Once a Trojan is removed, keep away from dubious sites and don’t install unknown browser extensions – you risk infecting the computer again. Pick Custom installation every time you install new software, and remember that malware like “CRITICAL ALERT FROM WINDOWS” comes in many variants – Critical Error, Microsoft Alert, and Windows Security Alert are just some of the examples. All of them need to be ignored and removed, without any exceptions.
