[QUOTE="Andy Ful, post: 1117319, member: 32260"] Why can the order of executed samples destroy the AV scoring in Leo's test? If the first sample was the "AV challenge", the test result would be 200 missed malware per 200 samples, even if all samples except the first were detected in another test without the "AV challenge" sample. A similar problem can arise if some samples can weaken the AV & Windows protection, without serious infection. If so, the next samples would have more chance of infecting the system. A clear example would be malware that managed to add folder exclusion in Microsoft Defender but was killed before doing more damage. [/QUOTE]
