Why am I seeing Your computer has been compromised message?

If you are seeing a message that says your computer has been compromised, it is likely a type of scam known as a tech support scam. 

These scams often involve a pop-up message or a phone call fronting a legitimate company such as Microsoft or Apple. They attempt to trick you into giving away personal or financial information or paying for unnecessary tech support services. 

Here are a few possible reasons why you may be seeing this message:

  • Malicious software – If you’ve downloaded malware or other malicious software onto your computer, it may cause the pop-up message to appear. Malware can infect your computer in various ways, such as through email attachments, fake software updates, or visiting malicious websites.
  • Phishing – Phishing is a scam where attackers attempt to trick you into providing sensitive information, such as your login credentials or credit card information. A pop-up message claiming that your computer has been compromised may be an attempt to get you to give away this information.
  • Adware – Adware is software that displays unwanted advertisements on your computer. Some types of adware may display fake security warnings to scare you into downloading more software or paying for unnecessary tech support services.

We have explored how to remove hackers from your Windows 10 computer, and depending on the severity of the issue, you might not have to use them all.
