What is antimalware, and which one should you choose to protect you from malware?
The cybersecurity company Kaspersky detected an average of 467,000 malicious files per day in 2024 (source: cyber-securite.fr). At the same time, ANSSI (Agence nationale de la sécurité des systèmes d'information) reported a 15% increase in malware attacks. These figures show just how important it is for companies to protect themselves against these threats in the virtual world.
In this article, we present the best anti-malware solutions, as well as the criteria for choosing your own software. Security is yours!
What is anti-malware?
Anti-malware: definition
Malware is a contraction of malicious software. It refers to an application whose purpose is to :
- corrupt a system,
- steal data,
- force access to a network,
- or spy on an activity.
This category includes viruses, ransomware, worms, Trojans, gootloaders, spyware, adware, etc.
🛡️ To counter this type of threat, cybersecurity experts have developed anti-malware technologies. Installed on computer workstations, their role is to detect, prevent and remove malware.
What's the difference between anti-virus and anti-malware software?
Antivirus software is a program used to defend a device against a particular type of threat: viruses.
But with the development of cyberthreats, technologies have also evolved to cover a wider range of defenses.
This is why we now speak of anti-malware software.
How does anti-malware protect you?
Detection and analysis
Antimalware detection is based on the signature of the malicious file. Specifically, the software looks for matches between the analyzed files and the malware database at its disposal. This method has become inadequate, particularly in the fight against zero-day threats. Detection performance is further enhanced by two other analysis methods:
-
Heuristic analysis, i.e. analysis of a program's behavior to detect suspicious activity.
-
Behavioral analysis: this involves proactive monitoring of all programs, with real-time intervention in the event of malicious action.
Blocking, quarantining and removing threats
If malware is detected, anti-malware immediately blocks its action. The suspicious file is then quarantined to prevent it spreading through your system.
👉 During this isolation, the threat is assessed by the software. Depending on the level of danger, you have 2 options:
- delete the infected file,
- or attempt disinfection.
Of course, you can also automate these processes depending on the threat.
Additional features: anti-phishing, ransomware and more
As threats become increasingly sophisticated, anti-malware software also evolves with ever more features. Today's anti-malware programs all include, either natively or as an optional module or premium package :
- protection against phishing,
- and ransomware.
Some also feature a VPN for secure company-wide browsing, whether in the office or on the move.
Scheduled scanning to optimize performance
Anti-malware solutions not only offer real-time protection, but also programmable options: scan during periods of inactivity, quick scan or customized scan. Thanks to this planning, you can minimize the impact of the software on your system's performance. ✅
Integrated firewall
A firewall monitors traffic entering and leaving your computer network. Based on predefined security rules, the tool blocks or authorizes traffic. An essential filtering element that represents the first barrier against malware intrusion attempts. ✋
What benefits can companies expect from antimalware?
1) Improved IT security
Antimalware software considerably increases the security of your IT system. No matter how dangerous the threats, it enables you to respond appropriately to limit the risks. Your network is protected at every level, from individual workstations to central servers.
2) Protection for your sensitive data
In today's digital ecosystem, data protection is a major issue. By using high-performance anti-malware, you reduce the risk of theft or corruption of your sensitive data.
3) Better system performance
People tend to think that anti-malware software slows down IS. In fact, the opposite is true! They help optimize your performance. By ridding you of malware or unwanted programs, they enable your devices to run more smoothly and efficiently.
Modern anti-malware solutions adapt their level of action to your use. So you can maintain a perfect balance between security and performance.
4) Peace of mind for employees
Installing a reliable, high-performance anti-malware solution brings real peace of mind to your teams. A mental state that's essential for performance in a digital work environment, where browsing, downloading and file-sharing take place on a daily basis.
The confidence provided by security software allows your staff to focus on their tasks, rather than on potential cybersecurity issues. For best results, reinforce the IT security culture within your organization with training and awareness-raising in cyber best practices.

How to choose antimalware? Criteria and selection guide
Software detection efficiency
The number 1 priority when selecting an anti-malware product is its detection rate. Take an interest in the results of independent tests (AV-Test or AV-Comparatives) of the software you are interested in. The product of your choice should score close to 100%.
Performance, compatibility and lightness
Always check the technical specifications required to run an anti-malware product on your computer. Some anti-malware suites are too heavy and risk slowing down your online activity. To avoid this inconvenience, turn to lightweight, unobtrusive software that's compatible with your computer system.
Ease of use and ergonomics
If your company doesn't have a full IT department, opt for an anti-malware program that's easy to use. An ergonomic tool will require fewer resources and less investment in training to be adopted by your teams.
Budget and value for money
Good anti-malware software also means a product that fits your budget. Quality protection is essential, but not at any price. Compare the various products on the market, and choose the best value for money solutions rather than the cheapest options. If you've got a lot of workstations to protect, you'll want to take advantage of a sliding scale of prices.
