If you’re one of the many people who own an operating system running Microsoft’s most popular operating system, you may be wondering if you need third-party antivirus software. Microsoft Windows 11 has hardware security features such as TPM 2.0 and Secure Boot, which prevent malware from infecting your PC during boot-up. These security tools are designed to ensure only authentic drivers and OS files are installed. They also ensure that malicious software cannot alter your system files or memory.

Microsoft’s Windows Defender doesn’t protect your device from all cyber threats. Be aware that even the most secured systems can be infected by malware, viruses and other ransomware. These threats can damage sensitive data, slow your machine down and even erase it.

In the end, it’s always a good idea to have a robust antivirus program protecting your Windows 11 machine. Its role is to block malicious websites and ads that contain viruses, so they won’t infect your computer or spread to others.

Some experts recommend the use of Microsoft’s built-in security functions together with a third-party antivirus application to increase your security online. It’s crucial not to overload yourself with layers of protection as they could interfere with one another and diminish their effectiveness. Multiple antivirus programs can be expensive and drain the resources of your system, resulting in slower performance.
