Abstract: A virus and malware cleaner is generated for a personal computer. Scanning software determines the presence of suspicious attributes resident to the computer. When automated detection of the need for a Custom Cleaner occurs, specific system information, along with information about the suspicious attributes, is included in a Custom Cleaner Request. The request is automatically generated and transmitted to a server for processing. In response a Custom Cleaner may be automatically created from a database of parameterized instructions, then downloaded to the user's computer for execution. Automatic verification of the Custom Cleaner success in removing infected files may be sent to the server. In the event that a Custom Cleaner cannot be generated automatically, an escalation occurs in which a support technician becomes involved in preparing the Custom Cleaner. Escalation data accessed by the support technician may include automatically generated diagnostic hints.

Abstract: Files are tested for presence of a predefined data pattern, such as a virus definition. For each one file of a first plurality of files, physical address data is derived from logical address information. Also, an entry is made in a first data structure. The entry includes file information and the derived physical address data. For each one cylinder of a hard drive, the first data structure is tested to identify any files having file contents stored in the cylinder. When the testing determines that the first data structure includes an entry having physical address data corresponding to the one cylinder, a read operation I requested to read the cylinder. Such testing and reading is repeated to read in multiple cylinders in a generally sequential order. The cylinder content is stored in a buffer. File content is read from the buffer for each one file of a second plurality of files. The read file content is tested for the presence of the predefined data pattern.

Abstract: In a multi-pole, double-throw switch, three multi-terminal device connectors are coupled to a printed circuit board, along with two header connectors and a movable array. A pcb trace electrically couples each terminal of each device connector to one or more corresponding contacts at the header connectors. The movable is movable between a first throw position in which a first header connector is engaged, and a second throw position in which a second header connector is engaged. In the first throw position, each terminal of a first of the three device connectors is electrically connected to a corresponding terminal of a second of the three device connectors. In the second throw position, each terminal of the first of the three device connectors is electrically connected to a corresponding terminal of a third of the three device connectors.

Abstract: Files stored on a hard disk drive are scanned for a predefined pattern, such as a virus definition. For each one of a plurality of files, predetermined select portion(s) (e.g., likely sites of infection) are stored in a common file. After storing the predetermined select portions, the portions are tested without accessing the file to determine whether content of the predetermined select portion corresponds to the predefined pattern.

Abstract: Files from a client are backed up over the internet onto a back-up storage area. The client gathers identifying information for each file, including file size and file checksum. A client server estimates whether the information matches that present in a database including identifying information from multiple clients. When the information for a given file is present, the matched information is stored in the back-up storage area. When the information is not present, the given file is received from the client computer. The given file and the associated identifying information then are stored in the back-up storage area. The backed-up files are accessible in online storage, and may be archived. The client accesses the backed-up files over the internet in a restore operation, or as a virtual hard disk, a virtual CD image or a virtual DVD image. The backed-up files are accessible offline on a CD or DVD.
