I need to speak to a technical support representative

Follow these steps to get protection working again and then contact support if needed.

1. Restart the laptop

• Close all apps and restart Windows. This can fix temporary issues with the Defender service.

2. Check that Microsoft Defender Antivirus service is running
3. Select Start and type services.msc, then press Enter.
4. In the Services window, find Windows Defender Antivirus Service.
5. Make sure Startup type is set to Automatic.
6. On the Action menu, select Start.
   • If Start is greyed out, select Stop, wait for it to stop, then select Start again.
7. Note any error messages that appear during this process.
8. Remove third‑party antivirus that may be disabling Defender Some third‑party security products can turn off Microsoft Defender.
9. Select Start, type appwiz.cpl, and press Enter.
10. In Programs and Features, uninstall any non‑Microsoft antivirus or security suites.
11. Restart the laptop.
    • Caution: While third‑party security is removed and before Defender is working, the device may be unprotected.
12. Run Microsoft malware tools once Defender is working If Defender starts successfully but still reports issues:
13. Run a full scan with the built‑in Malicious Software Removal Tool:
    • Press Windows logo key + R.
    • Type %windir%\system32\mrt.exe and select OK.
    • Approve the prompt and follow the wizard to perform a full scan and clean.
14. After the scan, restart the laptop.
15. Install the latest Windows and Defender updates from Settings → Windows Update.
16. If Defender still will not start or errors continue

• Run Windows Update to ensure the latest Defender components are installed.
• If Defender continues to show errors during scans or startup, use the Feedback Hub (Windows logo key + F) to report the issue and then contact Microsoft Support.

6. Contact a Microsoft support representative If the device still reports viruses and Defender remains disabled or cannot be started:

• Go to the Microsoft Support site and choose the Security or Windows Defender product family to reach support options.
• Alternatively, use the Get Help app in Windows:
  1. Open Start and search for Get Help.
  2. Describe the Defender/virus issue.
  3. Choose Contact support, then select chat or request a callback from a support agent.

If at any point malware prevents downloading tools like Microsoft Safety Scanner, a Microsoft Support agent may be able to download and run it remotely after you contact them.

Also be cautious of fake virus alerts or pop‑ups that tell you to call a phone number; real Microsoft warnings never include a phone number.
