Microsoft has done an excellent job adding new features and upgrading a lot of the functions that Windows Defender comes with.

Now having included ransomware protection, browser control, and device performance, the built-in antivirus can hold its own against most other antivirus utilities.

In the battle for the best free Windows antivirus between Windows Defender and Avast, Maximum PC choose Avast, but here’s what they said about Windows Defender:

Avast wins this bout by taking three of the five categories and tying in another, though it’s not quite as lopsided as it appears. Windows Defender, while not as fully featured as Avast, is capable of blocking common threats, and it doesn’t put a drain on system resources. Avast’s army of defenses is just bigger and better trained to spot danger from more places, like IM clients. It also has a bigger arsenal of weapons.

If you want extra protection or more features like email scanning, or machine learning to automatically block malware, then you might be better served by a third-party antivirus solution.
