FAQ
Why is Avast one of the best free antivirus solutions?
Avast’s free antivirus software combines cutting-edge, AI-driven cybersecurity with a massive threat-detection network of over 435 million users that lets us protect our entire community in real time against online threats whenever they appear.
Our industry-leading antivirus engine is just one of the many reasons why Avast Free Antivirus consistently earns high praise and top awards from PCMag, AV-Comparatives, AV-Test, and other independent experts. We have one of the best antivirus software solutions available, because we have the right antivirus protection for all your needs.
In 2021, Avast released a new and enhanced product called Avast One, which is now available in the United States, United Kingdom, Canada, Australia, Switzerland, France, and Germany.
How does Avast Free Antivirus protect against so many types of threats?
Trusted by over 435 million users around the world, Avast uses advanced machine learning techniques to protect against ransomware attacks and other emerging threats. Avast Free Antivirus software detects, blocks, and removes all types of malware: viruses, adware, spyware, Trojans, and more. You’ll also get security for your Wi-Fi network and real-time defense against phishing attacks, unsafe websites, and other threats to your devices.
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 — 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.
Will Avast One free antivirus software affect the performance of my device?
Avast One free antivirus software keeps your PC safe in real time without slowing it down. Get world-class protection against malware, phishing attacks, Wi-Fi threats, and more with our advanced cybersecurity tool that’s both comprehensive and light on your system’s resources.

How do I detect and remove viruses and other malware?
Avast’s free antivirus software detects and blocks all types of malware in real time to prevent them from infecting your computer. At the same time, it scans your PC to remove viruses and other malware automatically before they can do real damage.
If you’re up for a challenge, you can also try to remove viruses and malware the old fashioned way.
