Title:
コンピュータにおける悪意のあるソフトウェアの検出
Document Type and Number:
Japanese Patent JP2009520293
Kind Code:
A
Abstract:
A method of scanning for viruses in the memory of a computing device in which only memory pages marked as executable need to be scanned. The trigger for the scan can be either via an API that changes a page from writeable to executable, or via a kernel notification that an executable page has been modified. This invention is efficient, in that it makes much previous scanning of file systems redundant; this saves power and causes devices to execute faster. It is also more secure, as it detects viruses that other methods cannot reach, and does so at the point of execution.
