Yes, Windows 10 does need antivirus software. While Windows 10 has built-in security features, such as Windows Defender, that can help protect your computer from viruses and other malware, these features are not enough to provide complete protection. An antivirus program can provide an additional layer of protection, and can help to detect and remove malware that may have been missed by the built-in security features.

In addition to protecting your computer from viruses and other malware, an antivirus program can also help to protect your personal information and prevent unauthorized access to your files. This can be particularly important if you use your computer for online banking or other sensitive activities.

While there are many antivirus programs available for Windows 10, it is important to choose one that is reliable and well-reviewed. Some popular antivirus programs for Windows 10 include Avast, McAfee, and Kaspersky.

In conclusion, while Windows 10 has built-in security features, it is still recommended to use an antivirus program to provide additional protection for your computer. An antivirus program can help to protect your personal information, prevent unauthorized access to your files, and keep your computer safe from viruses and other malware.
