Important info for Windows XP users

Avast Free Antivirus still protects Windows XP owners with regular virus definition updates. But we no longer provide program updates, new features, bug fixes, or support for Windows XP. We strongly recommend upgrading to the latest version of Windows. (Remember, Microsoft ended its security updates for Windows XP back in 2014.)

Safe upgrade to Windows 10

Runs smoothly even on Windows XP

AV Comparatives called Avast "the antivirus with the lowest impact on PC performance." It has almost no impact on your Windows XP's performance. Plus, advanced features like Cleanup and Browser Cleanup make things run even faster.

Years and years using this software, I like it and lots of friends and family are using it too. If your computer is infected it goes straight to the base of your O.S. and kill the virus. Love it !
