“Warning: Activation Key Damage” pop-up is fake – do not contact the provided phone number

Crooks introduced another scam to terrorize the virtual world – “Warning: Activation Key Damage.” This message shows up in a pop-up and aims to mislead users that it comes from a legitimate source – Microsoft. However, it has nothing to do with the giant tech firm, as it is cybercrooks that are trying to mislead users and make them call the provided “tech support” number.

The message also informs users that the system has been blocked, and error code was encountered (due to an alleged virus infection) and they are about to lose their highly important data. The scam relies on spilling as much information that some users don't understand, and hoping that they get deceived by it. If you have encountered such an alert, you should ignore it, close down the browser and check your system for adware.

Name Warning: Activation Key Damage
Type Tech support scam, hoax, online fraud
Cause If you are frequently redirected to this scam page, you are likely to be infected with adware variant Rogue.Tech-Support-Scam
Aim To mislead users and make them believe that their system is damaged/infected with malware; the only way to allegedly remediate this situation is to contact the alleged technicians
Removal You can uninstall adware with the help of robust security tools such as SpyHunterCombo Cleaner
System fix Adware and malware can seriously damage you core Windows system files. Remediate the machine with FortectIntego repair

While what crooks are saying is completely falsified – they have no way of checking whether your machine is infected – you should keep in mind that frequent redirects to shady websites can be a sign of adware infection. In this case, the adware can be detected by several security programs (SpyHunterCombo Cleaner included), and is commonly labelled as Rogue.Tech-Support-Scam.

According to its peculiarities, the adware falls into the category of tech support scams. They have been on the rise and, unfortunately, their deception techniques seem to successful. They are not identical but share common features. However, if you know the main quality, you get the key to solving the riddle. In other words, you can distinguish whether you encounter a real issue or happen to be targeted by hackers.

In the case, by showing Warning: Activation Key Damage ads or alerts, the threat actors hinder your browsing sessions. Specifically, while scrolling down in a website, you might be taken by a surprise when a message appears saying that an activation key was damaged, and you need to enter the password.

In addition, it advises calling the indicated number. Keep in mind that none of real error or security warning messages would provide a contact number, so it is one of the easiest way to tell the the message is entirely fake.

Do not expect this technical support expert to help you as he is only a mere crook looking for the opportunity to sell its questionable products. Not only might they be futile tools, but such programs might also be “enhanced” with virulent elements. If they start operating on the system, other applications might malfunction, or the general PC performance might decrease.

Lastly, we would like to warn you of “Warning: Activation Key Damage” redirect as well. When trying to exit the fake message, you might be directed to their host website which gives explicit instructions on how to solve the issue. Note that such domain might be infected. Thus, exit it and proceed to eliminate the adware. FortectIntego speeds up the procedure.

The transmission ways of the malware

By nature, these tech support scams possess more complex features than ordinary adware as they can cause plenty of problems. However, their distribution does not differ much from the PUPs. You might have accidentally enabled adware when you downloaded new software and then recklessly installed it. The malware hid under “Recommended” settings.

Since the majority of users tend to choose them and then carelessly speed through the stages, the PUP avoids detection. We would like to advise you to be more attentive throughout the installation and choose “Custom” instead of “Recommended” settings. Remove the checkmarks of the unnecessary programs and proceed to install the wanted app.

Delete adware from your system to recover from online scams

The so-called “Warning: Activation Key Damage” virus redirects are likely to be caused by a malicious program that is installed on your system. Unfortunately, the name of it might be disguised, or it might not even be visible at all. Therefore, the best way to get rid of malware is by performing a full system scan with security software and then cleaning the web browsers as we explain below.

If you have already contacted the crooks and allowed them to connect to your PC remotely, you should change all personal passwords for all your accounts. Also, if you were tricked into paying for some fake services, you should contact your bank and explain what happened – you might be able to dispute the charges.
