Abstract
A method scans a second web page linked to a first web page being displayed by a browser. The method identifies 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 before receiving the user selection of the target link. The method scans the prefetched content for a security threat, within the safe cache, which is configured to prevent the prefetched content from altering a memory or storage location external to the safe cache. The method detects user placement of a cursor proximate to the target link and, in response to identifying a security threat, presents a warning to the user, or in response to identifying no threat or the user opting to ignore the warning, causing display of a second window comprising the prefetched content.
