Abstract
A reputation server is coupled to multiple clients via a network. Each client has a security module that detect malware at the client. The security module computes a hygiene score based on detected malware and provides it to the reputation server. The security module monitors client encounters with entities such as files, programs, and websites. When a client encounters an entity, the security module obtains a reputation score for the entity from the reputation server. The security module evaluates the reputation score and optionally cancels an activity involving the entity. The reputation server computes reputation scores for the entities based on the clients' hygiene scores and operations performed in response to the evaluations. The reputation server prioritizes malware submissions from the client security modules based on the reputation scores.
