Windows Activation Error code 0x44578 keeping users out of their PC

Recently, a number of users have reported one particularly annoying message that makes them unable to use their PC’s whatsoever. The name of the error is Windows Activation Error code 0x44578 and once it gets displayed on your computer, it covers your whole screen, making it seemingly impossible to access anything or remove the error message in any way. People have tried terminating it via the task manager or by using different key combinations like Alt+Tab, Alt+F4, Ctrl+Alt+Delete and others. Unfortunately none of these seem to have worked. Therefore, if you get that error, you won’t be able to access anything on your PC. Normally, no Windows error should be that obstructive and bothersome. In fact, the truth is that this message is not an error message at all. Instead, it is a simple scam similar to most Ransomware viruses, a malicious program that seeks to get your money. What you actually see is a message made to look like an error in order to trick users into believing it. If you are one of those unlucky users who have experienced having their PC locked by Windows Activation Error code 0x44578, make sure that you read this whole article. Here you can find some crucial information regarding Ransomware programs such as this one and how you can deal with them. Down below, there’s also a detailed guide that can help you remove the “error message” that is locking your screen without the need to do what it tells you to.

How does the virus work?

Once inside your machine, the malicious software “locks” your PC by covering your whole screen with the obstructive message – this essentially prevents you from doing anything on your machine apart from interacting with the error message. As we already said, this message is specifically made to look as a legitimate Windows error. However, it is not. In most cases, the “error” has something to do with your production key. You’d probably have to type it inside a text field in order to confirm that your windows version is legit. However, because this is a scam made to get your money, even if you type in your actual key, it’d be identified as unreal/wrong. Surely, somewhere on the message screen, there would be some phone numbers that you are supposed to call in case you cannot confirm your production key. Do not call them – this is all a scam. Users who have made the phone call have been told that their production keys are invalid and that they need to pay a certain amount of money in order to get a valid key. By now, you should have realized how this scam works. It is all about you paying money to some hacker that has locked your PC through a Ransomware virus. Surely, this particular malicious program operates a bit differently than most other Ransomware viruses. Still, the end goal is the same. Therefore, we strongly recommend our users to avoid both calling the presented phone numbers and agreeing to pay the demanded money. After all, this is a ruse and it has nothing to do with your Windows key actually being invalid.

What to do?

As we mentioned in the beginning of this article, your best option is to make use of our Ransomware removal guide that you can find down below. Fortunately, this virus is not as sophisticated as some of the more malicious Ransomware programs out there. There is no encryption to be decoded and as long as you remain calm, keep your cool and follow our instructions, everything should be fine. Just remember, do not contact with the blackmailer and do not obey his bidding – nothing good will come out of this.

How to avoid any further infections?

Viruses like this one are nasty and now it should be clear for you just how important it is to keep your PC well protected. From now on, make sure that you always have a reliable anti-virus software that is frequently updated. Also, you have probably landed the virus by visiting and/or downloading files from some shady/illegal sites. Our advice for you is to stay from any web addresses that seem suspicious and might hold harmful contents. Stick to reputable and trustworthy websites, while avoiding the darker corners of the web. Also, be careful with any spam and questionable e-mails. After all, junk-mail is one of the most commonly employed methods for distributing harmful software, and the Ransomware in question is probably no exception. All in all, use your common sense when surfing the net, because this can save you a lot of time and money in the long run.
