Abstract
A unique session key is created for each execution of anti-virus software and is used to create a session stamp for each file scanned during that execution. The session stamp is stored in the directory entry for the file. When a request for the file is made, the anti-virus software uses the current session key to validate the session stamp. An invalid or absent session stamp indicates that the file needs to be scanned.
