Key Features
Free Malware Protection
Real-time malware scanning and removal — no subscription required, with detection rates competitive with paid products.
Limited Free VPN
5GB/week VPN included in the free plan — enough for occasional public Wi-Fi use.
Data Breach Monitoring
Checks your email addresses against known breach databases and alerts you when your information is found.
Performance Optimizer
Identifies junk files, startup slowdowns, and performance issues alongside security scanning.
Our Verdict
Avast One is the most capable free antivirus available — its free tier includes features that competitors charge for. The 2020 controversy over Avast selling user browsing data through its Jumpshot subsidiary is worth knowing about; Avast shut down Jumpshot and made privacy commitments, but privacy-conscious users may prefer Bitdefender or ESET. For users who prioritize features over privacy concerns, Avast One's free tier is genuinely impressive.
What Other Reviewers Say
The following quotes are credited to their original sources and are not written by Safety 1st Consumer Protection.
"Avast One is the most feature-rich free antivirus available. Its free tier includes a VPN, breach monitoring, and performance tools that competitors charge for — though the 2020 data-selling controversy is worth keeping in mind."
"Avast One's free plan is genuinely impressive — it includes more features than most paid antivirus products. The privacy history is a legitimate concern, but Avast has made meaningful changes since the Jumpshot shutdown."
