Claim:
A computer-implemented method of analyzing content for a security threat, the method comprising: identifying on a client computing device a target link to the content, wherein the target link is identified from one or more links to content that are contained within an open document on the client computing device, wherein the one or more links are prioritized by the client computing device to determine a prefetching order according to criteria specified by a user of the client computing device, and wherein the target link is identified and prioritized before a request for the content is sent from the client computing device to a computing device that stores the content; loading the content into a safe cache on the client computing device, according to the prefetching order and before receiving a user selection of the target link and the content is opened by an application configured to provide access to the content on the client computing device; while the content is in the safe cache: preventing the content from altering a memory location or storage location external to the safe cache; and scanning the content on the client computing device for a security threat; and before receiving the user selection of the target link, displaying an indicator to indicate whether a security threat was detected within the content.
