摘要： A system and method for efficiently determining that a received file is not malware is presented. In operation, when a file is received at a computing device, an evaluation is made as to whether the file includes user-modifiable, or superficial, data areas, i.e., areas of the file that by their nature do not typically carry or embed malware. If the file includes superficial data areas, those superficial data areas are filtered out and a file signature is generated based on the remaining portions of the received file. The file can then be compared to a list of know malware to determine if the file is malware. Alternatively, the file can be compared to a list of known, trusted files to determine whether the file is trustworthy.

摘要： Campaign detection techniques are described. In implementations, a signature is computed for each of a plurality of emails to be communicated by a service provider to respective intended recipients. A determination is made that two or more of the plurality of emails is similar based on the respective signatures. Responsive to a finding that a number of similar emails exceeds a threshold, an indication is output that the similar emails have a likelihood of being involved in a spam campaign.

摘要： Systems for providing sign-up email addresses are disclosed herein. A user may set up a sign-up email address for receiving emails from a trusted, Internet-based enterprise. The user may set up a dedicated mailbox folder associated with the sign-up email address or enterprise. The email server may automatically direct emails coming from that enterprise into that folder. To “unsubscribe,” the user needs only to delete the folder or the sign-up address. Emails from the enterprise to the sign-up address may be highlighted in the user's main inbox. Thus, the user may be assured that any such email is truly from the enterprise, and not a phishing expedition or spam. Such systems also provide the user with effective tools to recognize phish or spam emails that appear to be from the trusted enterprise and not to act on them.

摘要： Techniques for eliminating duplicate/redundant scanning of email messages while the email message traverses the various servers within an email infrastructure are provided. Some techniques utilize a message hygiene stamp that is transported with the email message as the email message enters an enterprise and is routed within the enterprise until the email message reaches the end user inbox. The filters comprise logic that enables the filters to annotate the result of their filtering or other processing in corresponding message hygiene stamps. The message hygiene stamps allow the filters to determine whether the email message has already been processed by the filter within the email infrastructure.

摘要： Propagating messaging preferences of one or more users from a recipient mailbox to a perimeter network administering e-mail content blocking and routing. A content filtering application located outside a trusted network receives messaging preferences information from within the trusted network regarding the mail recipients. This messaging preferences information may be utilized to allow certain pre-authorized messages from particular senders to bypass content filtering. Moreover, the messaging preferences information may be hashed to further protect the information on the perimeter network and to speed in review and comparison of the messaging preferences information. In addition, other types of user-specific information may be propagated to the perimeter network for use with other applications other than messaging.

摘要： A user defines mutually exclusive inbox and spam folders to which emails are routed based on a rating assigned to each email. A variable user-defined range defines a mapping of the ratings to each folder. Incoming emails are routing to one of the folders according to the range. A reference set of emails is designated, each having a rating and either an inbox label or a spam label. A display indicates the number the reference emails in each folder if the reference emails are routed to one of the folders according to their ratings and according to the user-defined range.

摘要： The present invention causes rescue software to be updated when a secondary operating system is “booted” from a rescue disk. Aspects of the present invention may cause a computer to be “booted” using the rescue software when a user turns on a computer. Once the computer is booted using the rescue software, a source where a software update to the rescue software may be obtained is identified. Then, a determination is made regarding whether the software update originates from a trusted entity. In instances when the software update originates from a trusted entity, the rescue software is updated with one or more software updates.

摘要： In accordance with this invention, a system, method, and computer-readable medium that aggregates the knowledge base of a plurality of antivirus software applications are provided. User mode applications, such as antivirus software applications, gain access to file system operations through a common information model, which obviates the need for antivirus software vendors to create kernel mode filters. When file system operations are available to antivirus software applications, the present invention may cause each antivirus software application installed on a computing device to perform a scan to determine if the data is malware.
