Avast has earned many accolades, but the best reward is the loyalty of our 230 million users. We enjoy serving the largest community of any antivirus company in the world — and we’re thrilled to be able to continue to protect you when you upgrade your PC to Windows 10.
Windows 10 provides very basic protection. Avast Antivirus secures not only your PC, but your entire home network as well — and it comes with advanced features such as Software Updater, Passwords and more.
With Microsoft and Avast in your corner, there’s not much that can get in your way. With Microsoft supporting Avast Antivirus to work on all Windows 10 machines, it sends one clear message: we’re respected for what we do. That’s why industry experts like PC Magazine and PC Advisor rate us highly too.
We’re proud to be called the "Antivirus with the lowest impact on PC performance” by AV Comparatives. Whether you use your PC for gaming or for work, Avast gives you the biggest protection in the smallest package possible
Avast provides all the essential antivirus protection you need for your Windows 10 PC. But we don’t stop there. We offer extra security features such as a password manager, remote assistance, browser cleaning and more — yep, you guessed it — completely free.
We’re proud to protect millions of Windows 10 PCs. But you don’t have to take our word for it: Check to see how many PCs we’ve protected this week alone.

If you’re planning on upgrading from older versions of Windows, such as Vista, 7, 8, or 8.1, we’re ready to keep your new Windows 10 PC virus-free. Just make sure you’re running the latest version of Avast before you upgrade your machine, and when you finish the transition to Windows 10, you’ll find us there, right where you left us, ready to protect your PC and everything you hold dear in it.
It doesn’t take much to have a machine protected by Avast. All you need is a PC with 256 MB+ RAM and 1.5 GB of hard disk space. If your Windows 10 PC has that (which it very likely should), you’ll be good to go.
After all, we’re here to serve you.

Windows 10’s security is basic and oftentimes insufficient to protect you from every danger online. Avast Antivirus is more than equal to the task, however, and can offer your PC full protection without compromising its performance. Additionally, we offer features that your built-in protection simply doesn’t have, such as a password manager and remote assistance.
No. Hackers and programmers of malware become intimately familiar with built-in antivirus software, like Windows Defender, and they design their programs to work around them. Additionally, the built-in software gets updated less frequently than dedicated antivirus software, so it can’t protect you from the latest threats. While it will protect you from certain dangers, for top-of-the-line, full protection, you need Avast.
Not at all. Avast is designed from the ground up to be lightweight and accessible, and to protect your PC without leaving so much as a dent in your computer’s performance. Just install it and enjoy a PC free from malware and other threats.
