What You Need to Know About Antivirus Software Data Collection and Privacy

Antivirus software is essential for protecting devices and personal data from cyber threats, but a 2023 report by AV-Comparatives highlights significant concerns about how these programs collect and share user data.

The study examined 20 popular antivirus products, focusing on the types of data collected, user control over that data, sharing practices with third parties, and the transparency of privacy policies.

What Data Is Collected by Antivirus Software

Antivirus programs collect essential system information like operating system version, RAM, CPU type, and computer name to detect threats effectively. However, many also gather additional data such as BIOS details, installed applications, running processes, and network information including IP addresses and DNS servers.

User-specific data collected can include Windows usernames, time zone, language, location, and browsing activity if web protection features are enabled. Some antivirus software even uploads file names, locations, hashes, and occasionally entire files without explicit user consent.

Data Sharing Practices and Privacy Concerns

While some antivirus companies like F-Secure, G Data, and K7 demonstrate responsible data handling, others such as Norton, Panda, and McAfee have been criticized for sharing user data more freely. Notably, AVG (now part of Avast) was fined $16.5 million by the FTC for selling users’ browsing data to third-party advertisers.

Some data sharing supports malware detection collaboration, such as submitting suspicious files to VirusTotal, but transparency and user consent vary widely among vendors.

How to Protect Your Privacy When Using Antivirus Software

Users should proactively manage privacy settings within antivirus software to disable data collection features such as usage tracking, cloud analysis, and web activity logging. These options are often enabled by default, so reviewing settings after installation is crucial.

During installation, carefully read and uncheck any options related to data sharing or product improvement participation. Avoid free antivirus solutions that may monetize user data, and instead choose paid products from vendors with strong privacy reputations like F-Secure, ESET, and G Data.

Finally, reading privacy policies and end-user license agreements, or their simplified summaries, can provide valuable insight into what data is collected and how it is used.

Balancing Security and Privacy

Despite privacy concerns, antivirus software remains a critical defense against malware, phishing, and other cyber threats. The key is selecting products that provide strong protection while respecting user privacy and offering control over data collection.
