[QUOTE="cruelsister, post: 519520, member: 7463"] Let's consider the traditional (pure) AV solution: it will have a local scanner containing definitions against malware that would be uploaded to the system using the product at certain intervals. There will also be a Cloud component that would contain new malware definitions created after the last upload but still not pushed out. What can we expect in a test for this product? 1). When disconnected from the network, one can reasonably expect only the malware for which a local definition exists will be detected. It will not detect anything for which Cloud protection exists buy still not uploaded to the local system. In short detection should be lower with the Network disconnected. 2). A pure AV cannot detect anything for which it does not have a definition. So take an existing malicious file, nop out some redundant code and you get a brand new zero day file that the AV (Local or Cloud) cannot detect. Now let's review what the original video showed about C. 1). Detection went down in the absence of a Network connection 2). It did not detect malware files that have been modified. If it looks like a duck and quacks like a duck, then... [/QUOTE]
