Put an end to adware. Avast One scans and removes adware currently on your device, and stops future adware, viruses, and other types of threats. Best of all, it's 100% free and easy to use.
Avast finds and deletes adware and viruses faster and more thoroughly than any other adware scanner and cleaner on the market.
Renowned by experts for its powerful security features, Avast One’s “numerous excellent lab scores” are a major reason why PCMag named it a 2021 Editors’ Choice — describing Avast One as “a partner to keep you, your devices, and your data safe and happy.”
Meanwhile, TechRadar awarded Avast One a full 5 stars for its comprehensive anti-malware protection and prevention: “Avast One doesn’t just do a good job of detecting malware: it detects and blocks access to malicious websites, reducing the chance you’ll get infected in the first place.”
