[QUOTE="Andy Ful, post: 847668, member: 32260"] There is also an unknown impact on detection results related to the number of AV customers. [B]The AV1 with more customers can protect better than AV2 with fewer customers, even when both AVs have the same detection in AV tests.[/B] This cannot be easily calculated, because it can depend on malware prevalence, the number of new malware, and some other factors like the speed of protecting customers after the first infection (cloud response). The advantage of AV1 over AV2 takes place when the same unknown malware tries to attack several customers. For example, if the AV2 customers will be attacked 100 times by the same malware, then the AV1 customers will be attacked proportionally 100 *n1/n2 times, where n1 and n2 are numbers of customers and n1 > n2. But, if both AVs can protect just after the first attack, then there will be only 1 infected in AV1 group and 1 infected in AV2 group. Because the AV2 group is smaller, then the AV2 customer has greater chances to be hit by this malware. [/QUOTE]
