In the ever-evolving landscape of cybersecurity, the emergence of new threats like the x47.c botnet underscores the critical need for robust protection on home PCs. AV-Comparatives, a leading independent testing organization, has released its Malware Protection Test for September 2026, providing a comprehensive evaluation of 20 consumer security products. This test is particularly timely, as it addresses the growing risk that botnets pose to private users and small offices, who often lack dedicated IT support.
The test methodology is rigorous: it involves 10,000 malware samples, covering infection routes such as network drives, USB devices, and pre-existing disk infections. Each product is evaluated on its ability to prevent, detect, and reverse malicious actions, with a separate false alarm test ensuring that clean files are not incorrectly flagged. The results are a valuable resource for anyone looking to secure their digital life.
What is the AV-Comparatives Malware Protection Test?
The AV-Comparatives Malware Protection Test is a detailed assessment of consumer security software for Microsoft Windows. It simulates real-world scenarios where malware is already on the system or introduced via non-web vectors. Unlike the Real-World Protection Test, which focuses on web-based threats, this test covers file-based attacks that might come from USB drives, network shares, or downloaded files that evade initial scanning.

Each product is tested both with cloud connectivity and offline, to measure the impact of cloud-based detection. The test also includes a false alarm component, which is crucial because an overly sensitive product can block legitimate files and disrupt user workflows. The final award levels—ADVANCED+, ADVANCED, STANDARD, and TESTED—reflect both protection rates and the number of false alarms, offering a balanced view of each product’s performance.
What Stands Out in the September 2026 Test
Top Performers with ADVANCED+
Six products achieved the highest award: Bitdefender, ESET, G DATA, Kaspersky, Total Defense, and VIPRE. These products demonstrated exceptional protection against the 10,000 malware samples, with minimal false alarms. Their success highlights the importance of combining signature-based detection with behavioral analysis and cloud intelligence.
Cloud Dependency and Offline Detection
The test revealed significant variation in offline detection rates, ranging from 40.2% to 97.3%. This is a critical factor for users who may have unreliable internet connections or whose security software might lose access to its cloud service. Products with higher offline rates offer more consistent protection in such scenarios.
False Alarm Rates
Several products with high protection rates did not reach the top award due to elevated false alarm counts. This underscores the delicate balance between security and usability. A product that blocks too many legitimate files can be just as disruptive as a malware infection, making the false alarm test an essential part of the evaluation.
Threat Context: The x47.c Botnet
The test is set against the backdrop of the x47.c botnet, a new Windows threat that steals credentials, cookies, and crypto wallets, and can turn infected PCs into proxies or DDoS nodes. This real-world threat emphasizes the relevance of the test, as home users and small offices are prime targets for such malware.
Who It’s For
This test is an invaluable resource for home users, freelancers, and small business owners who want to make informed decisions about their security software. It provides clear, independent data that can help avoid the pitfalls of choosing a product based on marketing hype or brand recognition alone. For those managing a few devices on a single router, the test’s focus on file-based threats is particularly relevant, as a single infected device can compromise an entire network.
IT professionals and managed service providers can also benefit from the detailed results, which offer insights into the strengths and weaknesses of various products. The free access to the full report makes it a practical tool for anyone responsible for recommending or deploying security solutions.
Pricing and Availability
The full report is available free of charge on the AV-Comparatives website, without registration. This accessibility is a hallmark of AV-Comparatives’ mission to provide independent testing results to the public. While the test itself is free, the security products evaluated are commercial software with their own pricing structures, which users should consider when making a purchase decision.
AV-Comparatives also advises readers to look at multiple recent test reports, as well as factors like price, ease of use, compatibility, and support. Trying a free trial version is recommended to ensure the product fits one’s needs before committing.
What Makes It Worth Considering
The AV-Comparatives Malware Protection Test stands out for its transparency and rigor. The methodology is clearly documented, and the results are presented in a way that is accessible to non-experts. The inclusion of a false alarm test adds a layer of practicality that is often missing from other evaluations.
Moreover, the test’s timing, in light of the x47.c botnet, makes it highly relevant. It provides actionable insights into which products are best equipped to handle emerging threats, helping users protect their personal data and online activities. The fact that the report is free and easy to access further enhances its value as a consumer resource.
Verdict
AV-Comparatives’ Malware Protection Test September 2026 is a must-read for anyone serious about cybersecurity. It offers a clear, data-driven comparison of leading security products, highlighting the best performers and the importance of balanced protection. The test’s focus on real-world threats like the x47.c botnet makes it an essential tool for protecting home PCs and small office networks. Whether you’re a home user or a small business owner, this report can guide you to a security solution that offers reliable protection without unnecessary false alarms.
