Abstract: A method for protecting a data-storing device, the method including, when the data-storing device is connected to a first computing system, writing, using the first computing system, data associated to an autorun file within the data-storing device, in such a way that the autorun file is not accessible as such a file by an operating system running in a second computing system.

Abstract: A method for obtaining a classification of at least one identifier of at least one computer element is presented. The method involves the sending of identifiers between a sending client computing system and a plurality of receiving client computing systems, with the objective of obtaining a classification of said identifier, which corresponds to a computer element. Alternatively, if a predetermined condition of reception is not reached, a further sending of the identifier may be performed to a server computing system. This way, the classifications may be found spread over a plurality of receiving client computing systems or a server, and the data traffic may be distributed over several paths instead of, for example, a unique path to a unique server computing system.
