Abstract: A file copy is executed in a virtual runtime environment that tracks behavior using RNN taking runtime behavior of at least a first time into account with current runtime behavior at a second time. This is responsive to not finding a known signature for suspicious activity during virus scanning. A behavior sequence is identified on-the-fly during file copy execution that is indicative of malware, prior to completing the execution, the behavior sequence involving at least two actions taken at different times during file copy execution. Responsive to the identification, the execution is terminated and the virtual runtime environment is returned to the pool of available virtual runtime environments.

Abstract: Disclosed in one embodiment of the present invention is an electroplating apparatus and an electroplating method. The electroplating apparatus comprises a plurality of paddles arranged in parallel. The paddles move in a direction parallel to a substrate, and are used to stir electroplating solution.

According to the present invention, by designing the size and movement mode of the paddles, the accumulated time in which each corresponding point on the substrate is blocked by the paddles is equal, so that the received quantity of electricity is equal, and thus the consistency of an electroplating height is further improved.
