If you are among the many people who own a PC running on Microsoft’s most well-known operating system, you may be wondering if you need third-party antivirus software. Microsoft Windows 11 has hardware security features like TPM 2.0 and Secure Boot, which prevent malware from infecting your computer when it is booting up. These security tools ensure that only genuine OS and driver files are able to be installed. They also ensure that malicious software cannot alter the memory of your system or files.

Despite these strong built-in security measures, Microsoft’s Windows Defender isn’t enough to completely protect your device from all types of cyber-attacks. It’s important that you remember that even the most secure of systems can be infected with malware, viruses, and ransomware. These threats could harm your sensitive data, slow down your system’s performance, and erase your hard drive.

It’s therefore a good idea to always have a reliable antivirus program that protects your Windows 11 computer. Its function is to defend against spiteful virus-containing websites and ads, obstructing the access of these sites to your computer in order that they can’t be spread to other users or infect your files.

Some experts recommend using Microsoft’s built-in security tools with an antivirus program from a third party to ensure your digital security. It is important not to overdo the layers of protection as they could interfere and cancel out each other’s effectiveness. Using multiple antivirus programs can also be costly and consume your computer’s resources making it slower to run.
