MALICIOUS SOFTWARE PREVENTION USING SHARED INFORMATION

A method and apparatus for managing executable files. Responsive to detecting a request to run an executable file on a computer, a processor unit determines whether the executable file was downloaded to the computer within a period of time associated with a recent download. Responsive to a determination that the executable file was downloaded to the computer within the period of time, the processor unit determines whether feedback for the executable file from a number of users of the executable file is present in a repository. The feedback identified for the executable file in the repository is presented using a presentation system. User input as to whether the executable file should be run is prompted for by the processor unit after presenting the feedback.
