Adding "free" to this search usually means you want protection without paying, and you're wary that Avast's own site tends to default toward its paid Premium Security trial during setup. The free tier genuinely does exist and covers real-time antivirus scanning plus a Wi-Fi network inspector at no cost. Knowing which install prompts to decline keeps the whole setup free rather than sliding into a trial.
What's included free vs pushed into the paid upsell
The free tier covers real-time antivirus scanning, a Wi-Fi Inspector for checking network vulnerabilities, and basic firewall notifications.
Features like the ransomware file-shield, webcam protection and the built-in VPN are reserved for Avast Premium Security and get promoted heavily during installation. Declining those optional add-ons keeps the install strictly free.
Who ends up using Avast Free Antivirus
Home users wanting baseline malware protection without paying for a security subscription typically choose it.
- Everyday Windows users wanting real-time malware protection without a paid subscription
- Checking a home Wi-Fi network for vulnerable devices or weak router settings
- Running a one-off deep scan on a PC suspected of picking up malware
Before you install
A couple of things worth knowing about Avast Free Antivirus before you request the link: it covers Windows, macOS, Android and iOS, so pick the right build for the machine you're setting up. And on pricing, Avast Free Antivirus has a free tier plus a paid upgrade; the free build below is the full, genuine app, not a time-limited trial. It's developed and maintained by Avast (Gen Digital).
System requirements
- WindowsWindows 10 or 11 (64-bit); older 7/8.1 builds usually still run but no longer get official support
- macOSa recent macOS release — check the download page for the current minimum version, since Apple Silicon vs Intel builds sometimes differ
- Androida recent Android build installed from the Play Store or the developer's own APK
- iOSa recent iOS release installed from the App Store
Heavier workloads (large files, high-res media, big projects) will naturally want more RAM and a faster CPU/GPU than the bare minimum.
Quick steps
- Download the free installer and decline any bundled extras during setup
- Complete the install and skip the Premium trial prompt if you only want the free tier
- Let Avast run its first scan, then leave real-time protection running in the background
Avast Free Antivirus: the honest trade-offs
- Real-time scanning engine performs well in independent antivirus lab tests
- Wi-Fi Inspector adds network vulnerability checks most free antivirus tools skip
- Free tier has no time limit, unlike many competitors' 30-day trials
- Installer and setup screens push the paid Premium Security trial repeatedly
- Ransomware file-shield and webcam protection are reserved for the paid tier
This links to Avast's own free installer, not a reseller bundle, so you can decline every add-on cleanly during setup.

Keeping Avast Free Antivirus up to date
Avast Free Antivirus usually has a built-in updater or store-based auto-update (Microsoft Store / Mac App Store / Play Store, depending on platform); if you installed it manually, re-downloading the current build from the official source is the fallback. Sticking to the developer's own distribution channel — which is what this page links to — means you're never stuck on an old build with unpatched bugs just because a mirror site stopped updating its copy.

Frequently asked questions
Does Avast Free slow down an older PC?
It's noticeably lighter than the full Premium Security suite, though any real-time antivirus adds some background overhead on older hardware.
Is Avast Free different from AVG Free even though both are owned by Gen Digital?
They share much of the same scanning engine but keep separate interfaces and slightly different bundled extras.
