Abstract
A method scans a second web page linked to a first web page being displayed by a browser in a browser window. The method identifies, in the first web page, a target link to the second web page. Prior to receiving a user selection of the target link, the method prefetches content from the second web page and loads it into a safe cache according to a prefetching order before receiving the user selection of the target link and before the content of the second web page is opened by an application configured to provide access to the content of the second web page. The method scans the prefetched content from the second web page for a security threat, within the safe cache, which is configured to prevent the prefetched content from altering a memory location or storage location external to the safe cache.
