AV-Comparatives Business Security Test 2021 (August – November)

  1. This test shows how an antivirus behaves with certain threats, in a specific environment and under certain conditions.
    We encourage you to compare these results with others and take informed decisions on what security products to use.
    Before buying an antivirus you should consider factors such as price, ease of use, compatibility, and support. Installing a free trial version allows an antivirus to be tested in everyday use before purchase.

This is the second half-year report of our Business Main-Test Series of 2021, containing the results of the Business Real-World Protection Test (August-November), Business Malware Protection Test (September), Business Performance Test (November), as well as the Product Reviews.

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.

Test Procedure
The test series consists of three main parts:

The Real-World Protection Test mimics online malware attacks that a typical business user might encounter when surfing the Internet.

The Malware Protection Test considers a scenario in which the malware pre-exists on the disk or enters the test system via e.g. the local area network or removable device, rather than directly from the Internet.

In addition to each of the protection tests, a False-Positives Test is conducted, to check whether any products falsely identify legitimate software as harmful.

The Performance Test looks at the impact each product has on the system’s performance, i.e. how much it slows down normal use of the PC while performing certain tasks.

To complete the picture of each product’s capabilities, there is a user-interface review included in the report as well.

Some of the products in the test are clearly aimed at larger enterprises and organisations, while others are more applicable to smaller businesses. Please see each product’s review section for further details.
