It came second in the overall test, which included protection, usability and system load.
But it was the only product to score 100% in detecting malware; "AV-TEST examined the protection provided by the suites against the latest malware by making them fend off attacks by approximately 390 brand-new pieces of so-called “zero-day” malware in the real-world test. The second part of the scanning test used the AV-TEST reference set and required the packages to detect over 60,000 known pieces of malware that had been collected in the up to 4 weeks leading up to the start of the test."
Well done, F-Secure for another great test result.
