Modern operating systems include reasonably strong built-in protection, which changes what to look for in additional antivirus software.

What Built-In Protection Covers

Windows Defender and similar built-in tools now perform well against common malware in independent testing, covering baseline protection for most cautious users without any additional purchase.

When to Consider More

Additional software makes more sense for less cautious browsing habits, frequent downloads from varied sources, or added features like a VPN and identity monitoring bundled together. Avoid software that constantly nags with upsells or runs a heavy background footprint that slows the whole system down.

For most careful users, keeping built-in protection updated and enabled is genuinely sufficient day to day.
