Abstract: A method, computer program product or computer system for scanning files in a computer system to detect additional infected files of a computer virus when a first infected file of the computer virus is identified, includes maintaining a friends tree for each file in the computer system, maintaining a search tree using the friends trees for scanning the files, searching the files listed in the search tree for the additional infected files, and quarantining the additional infected files detected in the searching.

Abstract: Techniques are disclosed selecting a targeted advertisement to present to an individual, based upon the product preference of others and the individual's relationships with others. By analyzing content such as images and text, an individual's interest in a product or an individual's relationship with another person may be determined. Generally, a profile may store the above information and a relational product grid may provide an organized description of the relationships and product interests. The salability of a given product to a particular individual may be determined by analyzing the relational product grid. Based upon the salability, advertisers may decide whether to advertise a product to an individual. Thus, by leveraging personal relationship data, advertisers may expand their targeted advertising campaigns.

Abstract: A method of establishing a bi-directional grid computing network includes submitting a processing job from a job requester to a central repository, querying nodes associated with the job requester to process the processing job, identifying suitable nodes associated with the job requester to process the processing job, transmitting the processing job from the job requester to at least one of the suitable nodes associated with the job requester, processing the processing job on the at least one suitable node associated with the job requester, and returning results from processing the processing job to the job requester.
