Your computer has been compromised or hacked

While surfing the internet, some users have seen a popup message saying Your computer has been compromised or hacked. Different users have seen this message on different browsers, including Chrome, Firefox, Edge, etc. After getting this warning message, the affected users scanned their computers with the antivirus installed on their systems but the antivirus did not find any threat. If the antivirus threat report is clear, what does this message mean? Is this message real or fake? In this article, we will see what the Your computer has been compromised or hacked message means and what you should do if you see this message on your computer.

Your computer has been compromised or hacked

According to the feedback of the affected users, their web browser refuses to close after they receive the popup message. Also, a contact number is displayed along with the warning message. When they contacted that number, the support person asked them for some money to fix the problem. On the other hand, some users have also reported that after visiting a certain web page, instead of the warning popup message, they heard a voice saying “Your PC is hacked.”

Some users were also told to give access to their computers in order to resolve the issue. This is a spam and misleading message. You should ignore it otherwise, you will become the prey of hackers. Moreover, if you grant access to your computer to the person on the call, he/she might steal the data stored on your computer that may contain sensitive information.

Such types of warning messages usually display either a contact number or a link. We suggest you do not click on the link displayed in such types of warning messages. If you do so, a virus or malware may enter your system and may start sending your data to the hackers. Or, clicking on that link may install a program on your system. That program may contain a suspicious code. Such types of malicious programs are designed to change the registry keys on a user’s computer.

If you see a Your computer has been compromised or hacked warning message while surfing the internet, you should take the following steps immediately in order to protect your computer from malware or virus infection:

Disconnect your Internet connection

Open Windows 11/10 Settings.
Go to “Apps > Apps & Features.”

8] Run SFC and DISM scans

It is also possible that some of your system image files are damaged due to malware or virus infection. To check this, run an SFC scan. SFC stands for System File Checker. It is an automated tool developed by Microsoft that checks for damaged or corrupted system image files and repairs them (if possible).

We also suggest you run a DISM scan on your system. The DISM or Deployment Image Servicing and Management is a command-line tool. Like SFC, it also repairs the corrupted or damaged system image files. It is usually used when SFC fails to repair the system image files.

What does it mean if your computer is compromised?

A compromised computer is a computer, the confidentiality of which is adversely impacted, either intentionally or unintentionally. The term Compromised computer is usually used for hacked computers. There are many ways by which hackers can hack your system. The most common way is the phishing attempt. The phishing attempts are usually done by sending an email to the user with some suspicious links. When a user clicks on these links, he will be redirected to the website that looks exactly the same as the official website. These websites trick users and they enter their confidential information while signing in. In this way, hackers steal the confidential information of the users.

While surfing the internet via your web browser, some of you might have seen the messages similar to the following ones after visiting some specific websites:

Your computer might be at risk. Run a free antivirus scan to protect your computer.
Virus detected. Run a free antivirus scan to remove the virus from your computer.

Such types of websites are malicious websites. Clicking on any of the links on such websites installs malware on the user’s computer. After the malware is installed, a malicious code is executed on his/her computer and the hacker is able to steal the information from the infected computer. Some malware are also capable of changing the registry keys on a Windows computer.

TIP: Secure yourself, avoid online scams and know when to trust a website!

Does Microsoft call you about your computer being hacked?

Keep in mind that neither Microsoft nor its partners call you for your computer security issues. You need to learn how to identify scams that fraudulently use the Microsoft name. The motive of these calls is to steal the confidential data from the user’s computer so that they could use it for blackmailing purposes. The person on call may also ask to access your computer by installing a particular software. If you grant him/her access to your computer, he/she may execute a malicious code on your system or completely lock your computer. After that, the hacker will ask you for a certain amount of money to unlock your computer.

Hope this helps.
