AV-TEST The best Windows antivirus software for business users (August 2021)

  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.

During July and August 2021 we continuously evaluated 19 endpoint protection products using settings as provided by the vendor. We always used the most current publicly-available version of all products for the testing. They were allowed to update themselves at any time and query their in-the-cloud services. We focused on realistic test scenarios and challenged the products against real-world threats. Products had to demonstrate their capabilities using all components and protection layers.

It should be said that at the detection level, most antivirus software is similar (Cloud, AI Machine Learning, Heuristics etc).

I think that where we can differentiate them is on the interface and RAM consumption of the software...
Especially since these are business versions

( At work I love using Kaspersky and Eset because the interfaces do not change from the consumer version :D )
