It’s possible to wonder if you require third-party anti-virus software when you own a computer which runs Microsoft’s top-rated OS. After all, Microsoft Windows 11 boasts hardware security features such as TPM 2.0 and Secure Boot that prevent malware from infecting your computer as it starts up. These security tools are designed to ensure only genuine drivers and OS files can be installed. They also ensure that malware can’t alter your system’s files or memory.

Microsoft’s Windows Defender doesn’t protect your device against all cyber threats. Be aware that even the most secured systems can be attacked by malware, viruses and other ransomware. These threats can cause damage to your personal data, slow down the speed of your computer and erase your hard drive.

It’s always good to have a reliable antivirus program to safeguard your Windows 11 machine. Its role is to block harmful websites and advertisements that contain viruses, ensuring they don’t infect your PC or spread to others.

Some experts recommend mixing Microsoft built-in security with a third-party antivirus program to maximize digital safety. It’s important to not overdo the layers of security as they can potentially interfere and block the effectiveness of each other. Multiple antivirus programs can be costly and drain the resources of your system, resulting in slower performance.
