Abstract
Potentially malicious software is detected and prevented from installing and/or executing on client devices (122). A software developer sends software to a certifying authority (114) in order to obtain (710) a certification for the software. The certification uniquely identifies the software and allows any tampering to be detected. The software developer distributes (712) the software to the client devices (122). A client device (122) asks an execution authority (118) whether the software is malicious. The execution authority (118) maintains a database (514) specifying the status of certain software. If the status of the software at the client device (122) is in the database, the execution authority (118) reports it to the client device. The execution authority (118) can also analyze (716) the frequency of software execution requests from client devices (122) to determine whether the software is malicious.
