System Activation Key Has Expired

If a message claiming that your System Activation Key Has Expired is ever displayed to you during your browsing session, you must have entered an untrustworthy website or ended up on it against your will. We have to admit that System Activation Key Has Expired looks legitimate, but we also know for sure that it is a scam used by cyber criminals to make computer users call them. Yes, the message displayed to you will contain a telephone number, but you should not make a call by any means. What we expect you to do instead is to close System Activation Key Has Expired immediately and ignore the message it contains completely. Some users will not find it opened on their screens ever again, but you might not be so lucky. If the scam reappears on your screen, this suggests that it is opened to you by some kind of untrustworthy application that you have active on your computer. In most cases, it is an adware program. If you detect it on your PC, you must remove it ASAP because it is the only way to make sure the fake message is not shown to you ever again.

The fake System Activation Key Has Expired pop-up is shown to users seeking to convince them to call “technical support.” The targeted user is told that the system activation key has expired and, because of this, personal information, including passwords, messages, and credit cards, has been stolen from the computer. We can assure you that it is not true. You see the System Activation Key Has Expired warning because a) you have opened a dubious website/have been taken to it against your will, b) you have clicked on a malicious link, or c) there is an untrustworthy application installed on your computer. It is, probably, the last variant if you find it impossible to get rid of the System Activation Key Has Expired scam. As mentioned, adware programs are usually the ones responsible for showing fake messages. Do not let System Activation Key Has Expired convince you to make a call because there is no point in doing this when the problem it tells you about does not even exist. It is more likely that you will experience a lot of problems if you make a call because cyber criminals will pick up the phone and then will try to persuade you into purchasing a program you do not even need. Also, they might try to steal personal details, including your name, surname, address, etc. from you. Finally, they might try to gain access to your computer so that they could steal information from it/install malware directly.

It is not hard at all to find out what the reason the fake alert has been opened on your screen is. Simply try to close it. Has it reappeared? If not, it should not bother you ever again. If it is the opposite, i.e. the fake warning is opened to you again after some time, there must be an untrustworthy application installed on your computer. Most likely, it is an advertising-supported application, but other suspicious applications, e.g. potentially unwanted software might open the domain with this scam for you too. It is not very likely that you will know about the installation of suspicious software on your computer because they usually travel in software bundles and try to stay unnoticed. Do not let similar untrustworthy applications to enter your system unnoticed again in the future – keep your security application active. You should replace your old security tool with a new one because there is no doubt that it is unreliable if adware or another untrustworthy application has successfully entered your system and started doing its job.

If you cannot get rid of System Activation Key Has Expired, the first thing you should do is inspect all installed programs on your computer. Can you locate any programs you know nothing about? If so, it would be best to delete them all from the system. It is also advisable to reset browsers to default settings.
