Abstract: A charge/discharge circuit includes a power supply module, a switch module, an energy storage module, and a charge-discharge switching module connected in parallel. A first terminal of the energy storage module is connected to the switch module, and a second terminal of the energy storage module is connected to the charge-discharge switching module. The switch module and the charge-discharge switching module are configured to perform an action in response to a charge/discharge enable signal to produce an alternating current in the charge/discharge circuit. A waveform of the alternating current includes at least one of a triangular waveform, a quasi-triangular waveform, a sinusoidal waveform, or a quasi-sinusoidal waveform.

Abstract: Embodiments of the present disclosure provide a virus processing method and apparatus. In embodiments of the present disclosure, attribute analysis on the threads contained in the target process is performed to determine whether at least one of the threads contained in the target process matches virus attribute information. If at least one of the threads contained in the target process matches virus attribute information, virus type information is determined based on the matched virus attribute information, so that execution of process creation operation is prohibited based on the virus type information. Due to the measures of prohibiting execution of process creation operation, replication of virus in the system can be effectively prevented so as to improve security performance of the system.
