After installing the free Avast Antivirus (for Windows), it will be automatically activated for one year. You can use it freely without charge, but after 12 months, a prompt will tell you to activate again to continue using Avast Free Antivirus. Fortunately, it’s very easy to reactivate. You just have to follow these steps: * Right-click on the orange Avast icon in the notification area of your Windows taskbar. Select “Registration information.” * Go to the “My Subscriptions” tab and find the green “Upgrade now” button and click it. * Hover on the Avast Free Antivirus column and click “Select” at the bottom. * You’re done. You can double-check if your Free Avast is activated by clicking the X icon, which leads you back to the My Subscriptions screen.
