Abstract: An electric vehicle charging device includes a processing unit having a memory with a routine stored therein which, when executed by the processing unit causes the processing unit to control circuitry to prevent the electric vehicle charging device from charging an electric vehicle for a random delay period and to allow the electric vehicle charging device to charge the electric vehicle starting when the random delay period ends, wherein the random delay period starts at a predetermined start time and lasts a random delay length of time. The random delay reduces the peak load on a transformer that the electric vehicle charging device and other electric vehicle charging devices receive power from.

Abstract: An anti-malware system dynamically loads and unloads additional malware detection signatures based on a collection of data sources that indicate what signatures are relevant to a host machine in its current environment. A signature selector component determines what relevant signatures should be loaded. The signature selector component uses a variety of data sources either individually, or in combination, to determine relevancy of the available malware detection signatures. The anti-malware system dynamically determines which of the available malware detection signatures and classes of signatures are relevant and should be provided to a machine based on available information. The malware detection signatures are obtained and loaded automatically from one or more sources when a threat becomes relevant. A program or application may be blocked from accessing files until the relevant malware detection signatures have been loaded onto the machine.
