Where Avast Free Antivirus fits
Consider it when you want a dedicated security dashboard rather than relying solely on operating-system controls.
Check before you choose
Compare the installation options and paid upgrades with the protection already active on your device.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Start by checking the protection already running on your device. A permanent security suite, a portable scanner and a browser-cleanup utility are different interventions; installing several at once can complicate diagnosis.
