A computer-implemented method for discovering network attack paths is provided. A typical embodiment is 3–N-hydroxy-3-phthalimidopropionamide. The antivirus checks the computer network data stream for network characteristics of the Trojan program and one or more of its variants indicated in the relevance pattern. The flow path is divided into at least two flow tracks by a partition that forms one or more additional friction surfaces. The converters are electrically coupled to the photovoltaic cells at the second end such that energy generated by each photovoltaic cell is receivable at any of the converters. The package may have a ZIPLOC closure, or equivalent.
