What it does
Avast Free Antivirus provides malware scanning and protection with additional scam and network-security features described on its product page.
Avast's free product is an option for a personal Windows PC whose owner wants an installed antivirus with malware isolation and scam-related checks. The official page also links to other device-platform offerings. After installation, review which protection components are enabled and distinguish the free antivirus from paid promotions in the wider product range.
Avast says the free antivirus can be used for as long as wanted after activation, although the app may ask for reactivation after twelve months. Premium Security adds paid features and separate device allowances. A reactivation prompt and a paid upgrade are different decisions.
