Patent ID: 8635699

Claim:
A computer implemented method for optimizing scanning of digital content on read-only optical media, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising the steps of: detecting an optical medium being communicatively coupled to a computing device; determining whether the coupled optical medium is read-only; responsive to determining that the coupled optical medium is read-only: creating an identifying signature of the digital content on the coupled optical medium, based on the digital content thereon; searching a collection of stored data concerning digital content on read-only optical media for the created identifying signature; finding the created identifying signature in the collection of stored data concerning digital content on read-only optical media; responsive to finding the created identifying signature in the collection of stored data concerning digital content on read-only optical media, retrieving, from the collection of stored data, a stored scanning result for digital content identified by the found identifying signature; and instead of scanning the coupled optical medium, using the retrieved stored scanning result to determine a malware infection status of the coupled optical medium; and responsive to determining that the coupled optical medium is not read-only: scanning the optical medium to determine the malware infection status of the coupled optical medium.
