DESC: Rapid access to content is critical to the success of enterprises, service providers, and e-businesses. Content delivery can be accelerated and bottlenecks reduced by storing repetitive, bandwidth-consuming content closer to end-users and centrally managing its flow via the use of content-caching software and appliances. However, cached data can be an especially dangerous conduit for virus infection, because a single infected file can be repeatedly accessed by large numbers of users. Symantec AntiVirus technology provides a powerful and scalable solution to protect against the spread of viruses through caching devices. Today's blended threats include virus attacks that can propagate via HTTP and FTP traffic, making innocent Web surfing a vector for virus infection.
