A widely used antivirus with a well-known free tier, alongside paid plans that add ransomware protection, a firewall, and VPN.
Avast's free plan covers core virus scanning and browsing protection, while paid tiers add ransomware shields, a firewall, webcam protection, and VPN.
Use the button above so you land on Avast's real store page rather than a search result or ad.
Compare how many devices are covered and which extras (VPN, password manager, identity monitoring) are included at each tier.
You'll set up a login with your email and a password — this is what you'll use to manage your subscription later.
Enter billing details directly on Avast's official checkout to activate your license.
After purchasing, sign in on Avast's official site to reach your account dashboard.
From your dashboard, download the installer directly from Avast — avoid downloading antivirus software from anywhere other than the vendor's own site.
Open the downloaded file and follow the on-screen prompts. You may be asked to remove any existing antivirus first, since running two at once can cause conflicts.
The installer will ask you to sign in or enter the license key from your account to activate protection.
Once installed, run a full system scan to establish a clean baseline, then let real-time protection run in the background.
