摘要： During a bootstrapping process, path names of necessary bootstrap modules are collected and stored into a file. When an infected bootstrap component is detected, the method initiates emulation of the bootstrapping process within a virtual machine rather than directly cleaning malware from the infected bootstrap component. A settings file is copied into the virtual machine indicating the necessary bootstrap components in the host computer (including the infected component). Alternatively, the actual components are copied into the virtual machine. A clean version of the infected bootstrap component is made available to the virtual machine. The virtual machine is launched using the bootstrap components (including the clean version of the infected bootstrap component) and it emulates the bootstrapping process of the operating system. A successful bootstrap indicates the infected bootstrap component may be cleaned on the host computer. An unsuccessful bootstrap indicates the infected bootstrap component should not be cleaned of malware.
摘要翻译：在引导过程中，必需的引导模块的路径名被收集并存储到一个文件中。当检测到受感染的引导组件时，该方法将启动虚拟机中的引导过程的仿真，而不是直接从受感染的引导组件清除恶意软件。将设置文件复制到虚拟机中，指示主机中必需的引导组件（包括受感染的组件）。或者，将实际组件复制到虚拟机中。感染引导组件的干净版本可用于虚拟机。使用引导组件（包括受感染引导组件的干净版本）启动虚拟机，并且会模拟操作系统的引导过程。一个成功的引导指示受感染的引导组件可能在主机上清理。不成功的引导表示感染的引导组件不应该被清除恶意软件。

摘要： The present disclosure discloses an antenna device, which comprises an array antenna and a power divider. The array antenna comprises a plurality of antenna units, and each of the antenna units comprises a conductive sheet engraved with a groove topology pattern, conductive feeding points and a feeder line. The power divider is adapted to divide a baseband signal into a plurality of weighted signals and then transmit the weighted signals to the antenna units arranged in an array via the conductive feeding points respectively. By arraying the antenna units and using the beam forming method, the directionality of the antenna can be designed as needed through phase superposition between the antenna units; and then, a reflective metal plate is provided on the back side of the antenna so that a back lobe of the antenna is compressed. In this way, the miniaturized antenna array can obtain a high directionality.

摘要： A virtual machine is used to perform a raw scan for evasive malware on a host computer without requiring an interrupt or restart of a host operating system. An antivirus program installs a raw scanner virtual machine. The raw scanner virtual machine is triggered to scan files and memory for malware. The raw scan results are collected by the antivirus program for analysis, such as for use in generating a report or for removal of malware. The memory and files of the host are mapped to a guest space of the virtual machine.

摘要： A computer executes a suspicious software sample directly on its CPU in order to detect if the software sample is malicious. The software sample does not execute within a sandbox or virtual machine. Before the sample executes, a memory state of the computer is saved and a virtual disk file is created to bootstrap the computer at a later time. Malicious behavior of the software sample is collected while it executes and a report is generated. Hard disk access requests are redirected to a virtual disk file. The software sample does not detect that it is being analyzed. After execution of the sample, the computer is reverts to a clean state by bootstrapping the computer from the saved virtual disk file and then restoring the computer's volatile and non-volatile virtual memory from the saved memory state. A new software sample may then be executed and analyzed on the clean computer.
