Abstract
A method is provided for detecting viruses. According to the method, data is stored in a journal area of memory before changes embodied in the data are written to virtual memory. At least a first portion of the data in the journal area of memory is scanned for viruses. In some embodiments, a second portion of data that immediately precedes and/or immediately follows data to which the first portion of the data pertains is scanned for viruses. Preferably, the virtual memory includes a persistent storage device. Also provided is a system that includes a processor, a memory that includes virtual memory and a journal storage area, and a virus scanner controlled by the processor. The virus scanner scans the journal storage area for viruses.
