Privacy Controversy: What Happened
In 2019, a joint investigation revealed that Avast's subsidiary Jumpshot was selling anonymized user browsing data to third parties. Avast responded by:
- Shutting down Jumpshot entirely in January 2020
- Paying a $16.5 million FTC fine in 2024
- Being acquired by NortonLifeLock (now Gen Digital) in 2022
- Implementing stricter data privacy policies
Since the acquisition, Avast operates under Gen Digital's privacy framework and no longer collects or sells browsing data. We consider the issue resolved, but users who prioritize privacy above all may prefer Bitdefender or Norton.
App Experience and Daily Use
Avast One uses a modern, card-based dashboard that groups features into three categories: Device Protection, Privacy, and Performance. The interface is cleaner than previous Avast versions and less cluttered than Norton or McAfee. A status indicator at the top shows your overall protection level and flags any actions needed.
The Wi-Fi Inspector is a standout feature that scans your local network for vulnerabilities. It checks your router for weak passwords, open ports, DNS hijacking, and known firmware exploits. It also identifies all devices on your network and flags those with security issues. This is useful for home users who want to verify their router is properly secured without manually checking every setting.
Avast's free version is one of the most feature-rich free antivirus products available. Beyond basic real-time protection, it includes a limited VPN (5 GB per week), Wi-Fi Inspector, and a basic browser cleanup tool. The free version does show occasional prompts to upgrade, but they are less aggressive than they used to be. For users who want solid free protection without the limitations of Windows Defender, Avast One Essential is a strong choice.
