Abstract
The present invention provides a system, method, and computer-readable medium for identifying malware that is loaded in the memory of a computing device. Software routines implemented by the present invention track the state of pages loaded in memory using page table access bits available from a central processing unit. A page in memory may be in a state that is “unsafe” or potentially infected with malware. In this instance, the present invention calls a scan engine to search a page for malware before information on the page is executed.
