PEER COMPUTER BASED THREAT DETECTION

A threat detection event indicating a detection of a malware entity is identified at a client. Threat information associated with the malware entity is identified responsive to the threat detection event, the threat information for detecting the malware entity, wherein at least some of the threat information is unaffected by variance associated with the malware entity. The threat information is reported to a peer client of the client. Peer threat information describing a peer malware entity detected at the peer client is received at the client from the peer client via a network and used to examine the client for the peer malware entity.
