Do you need third-party antivirus on Windows computers?
Since Windows 10, Microsoft has included Microsoft Defender Antivirus as part of the operating system. It’s built in, always up to date, and provides excellent protection without the downsides of third-party antivirus software.
Why Microsoft Defender is enough
Microsoft Defender Antivirus is designed to work seamlessly with Windows. Because it’s built in, it already has the deep system access it needs, without the risks that come with installing additional security software. Independent testing consistently shows Defender performing on par with, and often better than, paid alternatives.
With Microsoft Defender, you get:
Real-time protection against viruses, ransomware, and malware.
Lightweight performance that doesn’t slow down your computer.
Automatic updates delivered through Windows Update.
No extra cost, as it’s already included in Windows.
What are the risks of third-party antivirus?
Many third-party antivirus tools require deep hooks into your system to monitor everything that happens on your computer. To do this, they effectively punch holes into Windows to gain access. While this gives them visibility, it also creates potential vulnerabilities. Malware can sometimes exploit these very same “holes” to gain deep-level access.
On top of that, third-party software can:
Slow down your computer.
Interrupt your work with unnecessary alerts.
Come bundled with upsells or unwanted add-ons.
