Question

My computer was locked by Microsoft Defender with a repeating message not to turn it off and call this number 1800 956 454. Is this how Microsoft Defender normally operates?

Answer 1

Microsoft Defender does not operate by locking your computer and displaying a message instructing you to call a phone number. This behavior is indicative of a tech support scam rather than legitimate Microsoft Defender operations. Microsoft does not send unsolicited messages or phone calls to request personal information or to fix your computer. If you encounter such messages, it is advisable to ignore them and not to call the provided number. Instead, you should run a full scan with Microsoft Defender Antivirus to check for any malware and ensure your system is secure.
