The independent IT-security institute AV-TEST ran a study this past November and December on fifteen leading brand products that protect Windows-based businesses. The unbiased lab always makes sure to test the software in its most updated default version, to most closely mimic the experience a typical user would have with it. They design the tests to be as realistic as possible, using real-world threats. All products are evaluated on protection, performance, and usability. Avast Business Antivirus scored high in all categories, notably blocking 100% of all the zero-day malware threats used in the study.
