Abstract

A stamp is created and associated with a computer file. The stamp includes the address locations of data in the file that may be infltrated by computer related viruses and / or malware. Using this stamp, an anti-virus program can identify the specific parts of the file that should be scanned for virus infection. Other data in the file are ignored during the scanning process.

Description

technical field [0001] The present invention relates generally to computer virus detection, and more particularly to virus scanning. Background technique [0002] Antivirus (AV) programs are designed to prevent computer viruses from infecting files residing in the file system. Generally speaking, the AV program is located between the user or the user's application program and the computer system to ensure that files infected by computer viruses will not be written into the file system. If infected files already reside on the file system, the AV program helps ensure that they are not executed or copied to other computers. [0003] The AV program scans computer files for known viruses by comparing each file to a list of "virus signatures" stored in a "virus signature file". Scanning can be done upon user request, when, for example, an application accesses a file on a mass storage device, or on a scheduled basis. Therefore, virus scanning is a resource-intensive (CPU and dis...
