摘要: A computer has a storage device that is infected with malicious software (malware). The malware uses stealth or rootkit techniques to hide itself in the storage device. A security module within the storage device detects the malware by comparing the files read from the storage device to those reported by the operating system. Upon detecting the malware, the security module prepares the computer for malware obfuscation by storing information describing the location of the malware, deploying an executable file, and configuring it to run on reboot. The executable file executes upon reboot and locates the data on the storage device associated with the malware. The executable file obfuscates the data so that the malware no longer loads at boot time, thereby disabling the rootkit technique. The computer reboots and the security module remediates the malware infection.

摘要: A computer includes a file system that supports virtualization. A scanning module identifies a file to be scanned for malware and a virtualized file detection module determines whether the file is virtualized. A file retrieval module locates a virtualized version of the file if the file is determined to be virtualized, and a malware detection module determines whether the virtualized version of the file contains malware. If malware is found, the malware detection module takes remedial action to address any security threat posed by the malware.
摘要翻译: 计算机包括支持虚拟化的文件系统。 扫描模块识别要扫描的恶意软件的文件,虚拟文件检测模块确定文件是否被虚拟化。 如果文件被确定为虚拟化,则文件检索模块定位文件的虚拟版本,并且恶意软件检测模块确定文件的虚拟版本是否包含恶意软件。 如果发现恶意软件,则恶意软件检测模块采取补救措施来解决恶意软件造成的任何安全威胁。

摘要: Malware with fake or misleading anti-malware user interfaces (UIs) are detected. Processes running on a computer system are monitored and their window creation events are detected. The structures of the created windows are retrieved to detect presence of UI features that are commonly presented in known fake or misleading anti-malware UIs (“fakeAVUIs”). If a window includes a UI feature commonly presented in known fakeAVUIs, that window is determined suspicious and additional tests are applied to determine the validity of information in the window. If the information in the window is determined invalid, then the process that created the window is determined to be malware and a remediating action is applied to the process.

摘要: An individualized time-to-live (TTL) is determined for a reputation score of a computer file. The TTL is determined based on the reputation score and the confidence in the reputation score. The confidence can be determined based on attributes such as the reputation score, an age of the file, and a prevalence of the file. The reputation score is used to determine whether the file is malicious during a validity period defined by the TTL, and discarded thereafter.
摘要翻译: 针对计算机文件的信誉分数确定个性化的生存时间(TTL)。 TTL是根据信誉评分和对信誉评分的信心确定的。 信心可以根据诸如信誉评分,文件的年龄以及文件的普遍性等属性来确定。 信誉分数用于确定在由TTL定义的有效期内文件是否恶意,之后丢弃。
