How do you choose your antivirus?
To choose an antivirus that's right for your business, you need one that's effective, easy to use and suited to your environment. In 2025, with the proliferation and sophistication of threats, this choice is more strategic than ever. Here are the essential criteria to guide you.
1. Quality of detection and speed of response
Not all antivirus products are equal when it comes to identifying threats. Choose a solution that combines several detection methods:
- classic signature
- heuristic analysis
- and behavioural detection.
This enables you to anticipate not only known viruses, but also new or mutant attacks, such as ransomware. A good antivirus must also offer effective real-time detection, to block threats as soon as they appear, before they compromise your data or systems.
2. Compatibility with your IT environment
Your antivirus must be perfectly compatible with the operating system(s) of your devices: Windows, Mac, Android, even Linux. This is a crucial point, because poor compatibility can lead to conflicts, security flaws or slowdowns.
✅ Also think about compatibility with your other business software and security tools, to avoid duplication or incompatibilities that would complicate IT management.
3. Ease of administration and centralised management
In an SME or a structure without a dedicated IT team, simplicity is king. Choose an antivirus that offers a centralised administration console, accessible in the cloud, so you can control the protection of all your devices from a single interface. This will save you having to intervene machine by machine and will make it easier to manage updates, alerts and security reports.
4. Additional value-added features
In addition to simple virus detection, modern antivirus software often includes additional functions:
- Integrated VPN to secure Internet connections, especially if you use teleworking or the cloud a lot.
- Advanced firewall to filter incoming and outgoing communications.
- Email protection to block phishing and malicious attachments.
- Control of peripheral devices (USB, external disks) to prevent infections via physical media.
- Vulnerability scanning to detect vulnerabilities in your software and system.
These options can be decisive depending on the size of your business and your sector of activity (e.g. financial services, healthcare, handling sensitive data).
5. Impact on device performance
An antivirus that is too heavy can slow down your computers and harm productivity. Test the impact of the solution on the speed of your devices, particularly if you are working on older machines. The ideal solution is an antivirus that runs in the background, consuming as few resources as possible, without compromising security.
6. Technical support and updates
Cyber security is a constant battle. Make sure that your supplier offers responsive and competent technical support, available at times that suit your business. Updates should be frequent, automatic and rapid, to incorporate the latest virus definitions and guard against new threats.
7. Budget and business model
Finally, the choice between free and paid antivirus depends on your budget, but also on your requirements.
- The free versions may be suitable for basic protection,
- but the advanced options, centralised management and support are generally reserved for the paid versions.
👉 Remember to assess value for money based on the features you really need.

Whether it's a free solution like Microsoft Defender or more comprehensive paid-for antivirus products like Bitdefender, Kaspersky or Sophos, the key is to find the right combination of performance, ease of use and enhanced protection.

Which antivirus should you choose? The FAQ!
Which antivirus is the most effective?
There is no single answer, because effectiveness depends on your environment and the threats you are targeting. However, solutions such as Bitdefender GravityZone, ESET or Kaspersky Small Office Security are regularly praised for their high detection rate and rapid response to new threats. The choice also depends on how easy they are to integrate and the additional features you need.
Are they all Windows or Mac compatible?
Most professional antivirus products are compatible with Windows and Mac, and sometimes also with Android and Linux. For example, Microsoft Defender is mainly optimised for Windows (surprising, you might say), while solutions such as Avast, ESET or Sophos offer cross-platform compatibility. Conclusion: always check the exact compatibility with your systems before making your choice.
Which is the most reliable free antivirus?
Microsoft Defender has established itself as the benchmark free antivirus, especially for Windows users. It offers solid native protection and benefits from automatic updates. Avast also offers an interesting free version, but the advanced features are reserved for the paid versions.
Is Windows Defender sufficient as an antivirus?
Windows Defender (now Microsoft Defender) is more than sufficient for basic protection, especially for SMEs with standard usage. Its native integration and low impact on performance make it a pragmatic choice. On the other hand, for advanced needs (enhanced protection, centralised management, VPN, e-mail filtering, etc.), you will need to turn to more comprehensive pay-as-you-go solutions.
