Why is Avast Free Antivirus even better than Windows Defender?
Now known as Microsoft Defender, Windows Defender isn’t enough to match leading third-party PC antivirus programs. While it’ll keep your computer relatively safe against most types of malware, its anti-phishing protection is limited to Microsoft Edge — you’ll need Avast Free Antivirus to protect you on other browsers like Chrome and Firefox. Microsoft Defender also doesn’t score quite as high with independent testing labs like AV-Comparatives.
