If you’re one of the millions of people who own a PC running on Microsoft’s most well-known operating system, you might be wondering if you still require 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 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 programs aren’t able to alter your system’s memory or files.

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

It’s always recommended to use an antivirus program that is robust and secure for your Windows 11 machine. Its main function is blocking malicious websites and ads that contain viruses, ensuring they don’t infect your PC or spread to others.

Some experts recommend the use of Microsoft’s built-in security functions with an antivirus program from a third party to maximize your digital safety. It is important not to overload the layers of security as they can potentially interfere and negate the effectiveness of each other. Multiple antivirus programs can be expensive and drain the resources of your computer, which can result in slower performance.
