What do you do if your computer starts blaring an alarm and says you can’t shut down because it is infected with Trojan viruses and it will delete your data. It says MS tech support, but ph # does not match what is online.

If your computer is blaring an alarm and displaying messages claiming it is infected with Trojan viruses, it is likely a tech support scam. Here are steps you can take:

1. Do Not Call the Number: The phone number provided in the message is likely a scam. Microsoft does not provide support through unsolicited calls.
2. Close the Browser: Try to close the browser window that is displaying the alarm. You can do this by pressing Alt + F4 repeatedly until the browser closes, or by using Ctrl + Shift + Escape to open Task Manager and end the browser process.
3. Restart Your Computer: If the browser does not close, you can hold the power button down until your computer turns off. This should stop the alarm.
4. Clear Your Browser Cache: After restarting, clear your browser's cache to remove any unwanted scripts or pop-ups. Instructions for clearing cache can be found for different browsers:
   • For Edge: Go to the settings and clear browsing data.
   • For Chrome: Visit the settings and clear browsing data.
   • For Firefox: Access the settings and clear cache.
5. Run a Security Scan: Use Microsoft Defender or another trusted antivirus software to scan your computer for any malware or viruses.
6. Install an Adblocker: To minimize the likelihood of encountering similar issues in the future, consider installing an adblocker extension in your browser.
7. Stay Informed: Familiarize yourself with common tech support scams to avoid falling for them in the future. Microsoft has resources available to help you recognize and protect yourself from these scams.

If you suspect your computer may actually be infected with malware, consider seeking help from a professional or using trusted antivirus tools to ensure your system is secure.

If your computer blares an alarm saying “Trojan virus, don’t shut down, call Microsoft", it usually means it’s a scam.

Don’t call the number. You should close your browser (or force‑quit it), and then restart your computer.

Your data is not being deleted. Your computer is not actually infected unless you downloaded something.
