This is a short fact sheet for our Business Main-Test Series, containing the results of the Business Malware Protection Test (September) and Business Real-World Protection Test (August-September). The full report, including the Performance Test and product reviews, will be released in December. To be certified in December 2021 as an “Approved Business Product” by AV-Comparatives, the tested products must score at least 90% in the Malware Protection Test with zero false alarms on common business software, and at least 90% in the overall Real-World Protection Test (i.e. over the course of four months), with less than one hundred false alarms on any clean software/websites (and with zero false alarms on common business software). Tested products must also avoid major performance issues (impact score must be below 40) and have fixed all reported bugs in order to gain certification.

Please note that the results of the Business Main-Test Series cannot be compared with the results of the Consumer Main-Test Series, as the tests are done at different times, with different sets, different settings, etc.

Starting from 2022, products will be required to have an FP rate on non-business files below the Remarkably High threshold.

Tested Products

The following products were tested under Windows 10 64-bit and are included in this factsheet:

Information about additional third-party engines/signatures used by some of the products: Acronis, Cisco, Cybereason, FireEye, G Data and VIPRE use the Bitdefender engine (in addition to their own protection features). VMware uses the Avira engine (in addition to their own protection features). G Data’s OutbreakShield is based on Cyren.

In business environments, and with business products in general, it is usual for products to be configured by the system administrator, in accordance with vendor’s guidelines, and so we invited all vendors to configure their respective products.

Only a few vendors provide their products with optimal default settings which are ready to use, and did therefore not change any settings.

Please keep in mind that the results reached in the Enterprise Main-Test Series were only achieved by applying the respective product configurations described here. Any setting listed here as enabled might be disabled in your environment, and vice versa. This influences the protection rates, false alarm rates and system impact. The applied settings are used across all our Enterprise Tests over the year. That is to say, we do not allow a vendor to change settings depending on the test. Otherwise, vendors could e.g. configure their respective products for maximum protection in the protection tests (which would reduce performance and increase false alarms), and maximum speed in the performance tests (thus reducing protection and false alarms). Please not that some enterprise products have all their protection features disabled by default, so the admin has to configure the product to get any protection.

Acronis: “Backup”, “Vulnerability assessment”, “Patch management” and “Data protection map” disabled.

VMware: policy set to “Advanced”.

Avast, K7, Kaspersky, Panda: default settings.

Test Results

Real-World Protection Test (August-September)

This fact sheet gives a brief overview of the results of the Business Real-World Protection Test run in August and September 2021. The overall business product reports (each covering four months) will be released in July and December. For more information about this Real-World Protection Test, please read the details available at The results are based on a test set consisting of 375 test cases (such as malicious URLs), tested from the beginning of August till the end of September.

  Blocked User dependent Compromised PROTECTION RATE
[Blocked % + (User dependent %)/2]*
False Alarms
Bitdefender, Kaspersky, Microsoft 375 100% 0
Avast 375 100% 1
Panda 375 100% 9
Acronis, VIPRE, VMware 374 1 99.7% 0
CrowdStrike, FireEye 374 1 99.7% 1
K7 374 1 99.7% 2
Fortinet 374 1 99.7% 10
Malwarebytes 373 2 99.5% 4
Sophos 371 2 2 99.2% 3
ESET 371 4 98.9% 0
G Data 371 4 98.9% 1
Elastic 371 4 98.9% 3
Cybereason 370 5 98.7% 1
Cisco 367 8 97.9% 0

* User-dependent cases are given half credit. For example, if a program blocks 80% by itself, and another 20% of cases are user-dependent, we give half credit for the 20%, i.e. 10%, so it gets 90% altogether.

Malware Protection Test (September)

The Malware Protection Test assesses a security program’s ability to protect a system against infection by malicious files before, during or after execution. The methodology used for each product tested is as follows. Prior to execution, all the test samples are subjected to on-access scans (if this feature is available) by the security program (e.g. while copying the files over the network). Any samples that have not been detected by the on-access scanner are then executed on the test system, with Internet/cloud access available, to allow e.g. behavioral detection features to come into play. If a product does not prevent or reverse all the changes made by a particular malware sample within a given time period, that test case is considered to be a miss. For this test, 1,016 recent malware samples were used.

False positive (false alarm) test with common business software

A false alarm test done with common business software was also performed. All tested products had zero false alarms on common business software.

The following chart shows the results of the Business Malware Protection Test:

  Malware Protection Rate False Alarms on common business software
G Data, Microsoft, Sophos
100% 0
Avast, Bitdefender, Cisco, Elastic
99.9% 0
Fortinet, VIPRE, VMware
99.8% 0
Acronis, Cybereason
99.6% 0
CrowsStrike, FireEye
99.4% 0
Kaspersky 99.0% 0
K7, Panda
98.6% 0
Malwarebytes 98.4% 0
98.2% 0


In order to better evaluate the products’ detection accuracy and file detection capabilities (ability to distinguish good files from malicious files), we also performed a false alarm test on non-business software and uncommon files. This is provided mainly just as additional information, especially for organisations which often use uncommon non-business software or their own self-developed software. The results do not affect the overall test score or the Approved Business Product award. The false alarms found were promptly fixed by the respective vendors.

FP rate Number of FPs on
non-business software
Very Low 0-5
Low 6-15
Medium/Average 16-35
High 36-80
Very High 81-125
Remarkably high >125


  FP rate on non-business software
Acronis, Avast, Cisco, ESET, G Data, Kaspersky, Microsoft Very low
Bitdefender, K7, VMware, Vipre Low
CrowdStrike , FireEye, MalwareBytes, Panda, Sophos Medium/Average
Elastic High
Very high
Cybereason, Fortinet Remarkably high


It should be noted that Cybereason and Fortinet had Remarkably High levels of false positives on non-business software. Administrators should consider whether this might create problems in their organisation’s specific environments. Starting from 2022, products will be required to have an FP rate on non-business files below the Remarkably High threshold in order to be approved. This is to ensure that tested products do not achieve higher protection scores by using excessively restrictive settings that can cause very high levels of false positives.
