Choosing an antivirus solution in 2024 is no longer just about comparing malware detection rates. The European regulatory framework, the increasing number of connected devices per household, and the performance gaps between software suites make the comparison more technical than it seems. What criteria truly distinguish antivirus and cybersecurity solutions when placed side by side on measurable data?
Cyber Resilience Act: What the European regulation changes for antivirus
The Cyber Resilience Act (CRA), regulation (EU) 2024/2847, changes the game for all security software sold in the European Union. Coming into effect in December 2024, it will be fully applicable from December 11, 2027, with an initial deadline of September 11, 2026, for vulnerability reporting obligations.
Specifically, antivirus vendors must now define a support period corresponding to the expected usage duration of the product, with a minimum of five years of security patches. This requirement alters the logic of annual subscriptions: an antivirus purchased today must receive updates for at least five years, even if the user does not renew their premium license.
The penalties for non-compliance are severe. Serious violations of cybersecurity requirements can lead to fines of up to 15 million euros or 2.5% of global annual revenue. For the end user, this means that vendors who neglect to monitor their products face financial risks that theoretically encourage them to maintain a consistent level of protection over time.
Before comparing the features of available suites, it is useful to check the Viruslab website to verify recent independent test results on major vendors.
Comparison table of antivirus criteria in 2024
Classic comparisons list dozens of products. The table below focuses on the criteria that actually vary from one suite to another and impact daily use.
| Criterion | What it measures | Why it matters |
|---|---|---|
| Real-time detection | Ability to block a malicious file before execution | Even a small gap (fraction of a percent) represents thousands of unblocked threats across a network |
| System impact | Measured slowdown during scans or routine tasks | A heavy suite pushes users to disable it, nullifying its protection |
| Devices covered by license | Number and type of supported OS (Windows, macOS, Android, iOS) | An average household has multiple devices across different systems |
| Guaranteed support duration | Period during which the vendor commits to providing patches | The CRA imposes a minimum of five years, but some vendors go beyond |
| Additional modules | Integrated VPN, password manager, parental controls | Avoids stacking separate subscriptions, but quality varies greatly |
This table does not rank products: it identifies the areas where gaps are measurable. Raw detection has become a less discriminating criterion among major suites, as most achieve very high scores in independent lab tests. In contrast, the impact on system performance remains the main differentiating factor in daily use.
Free vs. paid antivirus: where is the real gap
The question arises every year. Free antivirus solutions often provide basic detection comparable to the paid versions from the same vendor. The gap does not lie in the detection engine itself, but in the peripheral layers.
- Free versions generally do not include VPN, password manager, or enhanced banking protection. For limited use to standard web browsing, this absence does not pose a concrete problem.
- Technical support for free versions is limited to community forums. In the event of an active infection, the lack of direct assistance can delay resolution by several days.
- Signature updates sometimes arrive with a slight delay in free versions compared to premium versions, creating a narrow but real vulnerability window against zero-day threats.
For a user managing sensitive data (professional documents, multiple bank accesses), the paid version is justified by the peripheral modules, not by the detection engine. For occasional browsing, the free version of a recognized vendor covers most common risks.
Antivirus and GDPR: data collection by security suites
An antivirus inherently analyzes everything that transits on the machine. This privileged position raises a question rarely addressed in comparisons: what data does the antivirus itself collect?
Several vendors have been criticized in recent years for selling anonymized browsing data to third-party advertisers. The GDPR regulates this practice, but consent is often buried in the installation conditions that most users accept without reading.
When choosing an antivirus suite, checking the vendor’s privacy policy is as relevant a criterion as the detection rate. An antivirus that protects against malware but monetizes its users’ browsing habits shifts the problem without solving it.
Criteria for choosing an antivirus in 2024: summary by profile
Occasional personal use
A free antivirus from a recognized vendor is sufficient. Activating two-factor authentication on main accounts (email, banking) adds protection at no extra cost.
Multi-device family use
A paid suite with a multi-device license and integrated parental controls simplifies management. The determining criterion is compatibility with all household systems, not the number of displayed features.
Professional use or sensitive data
The presence of an integrated VPN, an advanced anti-phishing module, and responsive support justifies the extra cost. The vendor’s compliance with the CRA and transparency on data collection become criteria for selection in their own right.
The European regulatory framework, with the CRA applicable from 2026-2027, will force vendors to ensure longer support for their products. The effective support duration will become a selection criterion as critical as price. Comparing antivirus solutions solely on their detection rates is akin to evaluating a car based only on its top speed, ignoring braking and maintenance.
