Access to system restricted

It sounds like you may be experiencing a tech support scam or a malicious pop-up that is trying to trick you into calling a fake support number. Here are some steps you can take to resolve this issue:

1. Do Not Call the Number: Avoid calling the number displayed on your screen, as it is likely a scam.
2. Disconnect from the Internet: If possible, disconnect your PC from the internet to prevent any further malicious activity.
3. Restart Your Computer: Try restarting your computer in Safe Mode. This can help you regain access to your system without the interference of the malicious pop-up.
4. Run a Security Scan: Use your antivirus software to run a full system scan to detect and remove any malware.
5. Report the Scam: If you believe you have been targeted by a scam, report it to your local authorities or use the technical support scam form provided by Microsoft.

If the problem persists, consider seeking help from a trusted IT professional or contacting Microsoft Support directly for assistance.

Hi Oluwafisayo, I can imagine how stressful and alarming that situation must feel seeing a loud warning and being locked out of your PC can make anyone panic.

That warning is not real its a scam popup trying to scare you into calling a fake number. Just close the browser or restart your PC and then clear cache also run a malware scan and update Windows to keep your system safe.

Did this alert appear while browsing a website or immediately after starting your PC?

Best regards
