    摘要： Generally described, the present invention is directed at identifying malware. In one embodiment, a method is provided that performs a search for malware during the boot process. More specifically, the method causes a software module configured to scan for malware to be initialized at computer start up. Then, in response to identifying the occurrence of a scanning event, the method causes the software module to search computer memory for data that is characteristic of malware. If data characteristic of malware is identified, the method handles the malware infection.

    摘要： Aspects of the subject matter described herein relate to antivirus protection and transactions. In aspects, a filter detects that a file is participating in a transaction and then may cause the file to be scanned together with any changes that have made to the file during the transaction. After a file is scanned, a cache entry may be updated to indicate that the file is clean. The cache entry may be used subsequently for like-type states. For example, if the file was scanned inside a transaction, the cache entry may be used later in the transaction. If the file was scanned outside a transaction, the cache entry may be used later for requests pertaining to files not in a transaction. Cache entries may be discarded when they are invalid or no longer useful.

    摘要翻译： 本文所述主题的方面涉及防病毒保护和交易。 在方面，过滤器检测到文件正在参与事务，然后可能导致文件与事务中对文件所做的任何更改一起进行扫描。 扫描文件后，可能会更新缓存条目以指示文件干净。 缓存条目可以随后用于类型状态。 例如，如果文件在事务中被扫描，则高速缓存条目可以在事务中稍后使用。 如果文件在事务之外被扫描，则缓存条目可以稍后用于与不在事务中的文件相关的请求。 缓存条目无效或不再有用时可能会被丢弃。

    摘要： An anti-malware system that reduces the likelihood of detecting a false positive. The system is applied in an enterprise network in which a server receives reports of suspected malware from multiple hosts. Files on hosts suspected of containing malware are compared to control versions of those files. A match between a suspected file and a control version is used as an indication that the malware report is a false positive. Such an indication may be used in conjunction with other information, such as whether other hosts similarly report suspect files that match control versions or whether the malware report is generated by a recently changed component of the anti-malware system.

    摘要： Disclosed are systems, methods and computer program products for detection of malware with complex infection patterns. The system provides enhanced protection against malware by identifying potentially harmful software objects, monitoring execution of various processes and threads of potentially harmful objects, compiling contexts of events of execution of the monitored processes and threads, and merging contexts of related processes and threads. Based on the analysis of the individual and merged object contexts using malware behavior rules, the system allows detection of malicious objects that have simple and complex behavior patterns.

    摘要： The present invention is directed to a method and system for automatically classifying an application into an application group which is previously classified in a knowledge base. More specifically, a runtime behavior of an application is captured as a series of events which are monitored and recorded during the execution of the application. The series of events are analyzed to find a proper application group which shares common runtime behavior patterns with the application. The knowledge base of application groups is previously constructed based on a large number of sample applications. The construction of the knowledge base is done in such a manner that each sample application can be classified into application groups based on a set of classification rules in the knowledge base. The set of classification rules are applied to a new application in order to classify the new application into one of the application groups.

    摘要： A generic RootKit detector is disclosed that identifies when a malware, commonly known as RootKit, is resident on a computer. In one embodiment, the generic RootKit detector performs a method that compares the properties of different versions of a library used by the operating system to provide services to an application program. In this regard, when a library is loaded into memory, an aspect of the generic RootKit detector compares two versions of the library; a potentially infected version in memory and a second version stored in a protected state on a storage device. If certain properties of the first version of the library are different from the second version, a determination is made that a RootKit is infection the computer.

    摘要： A method and system in a computing device for performing security related functions as part of a process created to execute a software component that may be unrelated to security is provided. The security system provides security code that performs one or more security related functions. When a process is created to execute the code of a software component, the security system causes the security code to be executed before the execution of the code of the software component. One security related function of the security code may be to cause the operating system to maintain information about the process as long as the process exists. If the operating system later reports that the process no longer exists but the information is still being maintained, then the security system can assume that malware is attempting to hide the process.
