This report is an excerpt of the Business Security Test 2021 (March – June). For more details, please click here.


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 test1,008 recent malware samples were used.

Test Results

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

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. 

  Malware Protection Rate False Alarms on common business software
Avast, Bitdefender, G Data, VMWare
100% 0
Cybereason, FireEye, Panda, Vipre
99.9% 0
Acronis, CrowdStrike 99.8% 0
Cisco 99.7% 0
Kaspersky, Microsoft, Sophos 99.6% 0
ESET 99.3% 0
Fortinet 99.2% 0
K7, Malwarebytes 99.1% 0
Elastic 99.0% 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, and 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. Organisations which often use uncommon or non-business software, or their own self-developed software, might like to consider these results, however.

FP rate Number of FPs on
non-business software
Very low 0 – 5
Low 6 – 10
