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 — so you’ll need Avast Free Antivirus to protect you on other browsers like Chrome and Firefox. Microsoft Defender also doesn’t score quite as highly with independent testing labs like AV-Comparatives. For comprehensive threat protection on your PC, go with Avast — the world’s most trusted antivirus.
