Avast Premium Security review

Avast splits its scam tools into two tiers. The free Avast One app includes Scam Guardian, Web Guard for risky websites and the AI-powered Avast Assistant, which you can ask about a message or an offer that looks wrong. Premium Security adds Scam Guardian Pro: Email Guard connects to up to five email accounts on Gmail, Outlook and other providers and flags scams and infected attachments in your inbox, Call Guard blocks scam calls and labels spam or verified businesses, and Safe SMS checks text messages. Windows users also get deepfake video detection. On the US store, Premium Security costs $49.08 for the first year for 1 PC plus 1 mobile device, then renews at $77.99, and Windows buyers can try it free for 30 days without a card. It is a good fit for someone who wants a free start and pays only when they want inbox and call screening. The renewal jump and the Windows-only deepfake tool are the main drawbacks.
