A collection of stored data concerning digital content on read-only optical media is maintained. The data collection comprises signatures identifying specific releases of digital content stored on optical media, and results of scanning the specific releases for malware. The coupling of optical media to a computing device is detected. In response, an identifying signature of the digital content on the optical medium is created, and the data collection is searched for the signature. Where the signature is found in the data collection, the stored scanning result for the corresponding digital content is retrieved. Instead of scanning the coupled optical medium, the retrieved scanning result is used to determine its malware infection status. Where the signature is not found in the data collection, the optical medium is scanned for malware. |
