Abstract
A reputation server is coupled to multiple clients via a network. Each client has a security module that detects malware at the client. The security module computes a hygiene score based on detected malware. The security module provides the hygiene score and an identifier of a visited web site to a reputation server. The security module also provides identifiers of files encountered at specified web sites to the reputation server. The reputation server computes secondary hygiene scores for web sites based on the hygiene scores of the clients that visit the web sites. The reputation server further computes reputation scores for files based on the secondary hygiene scores of sites that host the files. The reputation server provides the reputation scores to the clients. A reputation score represents an assessment of whether the associated file is malicious.
