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.

Frequently Asked Questions

Is Avast safe to use in 2026?
Yes. Avast addressed its 2019 data-selling controversy by shutting down Jumpshot (its data analytics subsidiary) in 2020 and paying a $16.5 million fine. The company was acquired by NortonLifeLock (now Gen Digital) in 2022 and has since undergone privacy audits. Avast is now considered safe for personal use.
Is Avast Free good enough?
Avast One Essential (free) provides solid real-time protection, web scanning, and a limited VPN (5 GB/week). It is one of the most feature-rich free antivirus options. For basic protection, it is good enough. For ransomware protection, firewall, and full VPN, upgrade to the paid plan.
Is Avast better than Windows Defender?
Yes. Avast scores higher in independent malware detection tests, especially for zero-day threats and phishing. The free version also includes more features than Defender, such as a VPN and Wi-Fi security scanner. However, for paid antivirus, Bitdefender and Norton are better choices.
What is the difference between Avast and AVG?
Avast acquired AVG in 2016, and both products now share the same malware detection engine. Avast One is the primary product going forward, offering more features. AVG continues to exist but is essentially the same protection with a different interface. Choose Avast One for the most up-to-date experience.
Does Avast slow down your computer?
Avast has low system impact in our tests, similar to Norton. Boot time and file operations are minimally affected. The free version is particularly lightweight since it lacks some background features. Overall, Avast should not noticeably slow down modern computers.
