The virtual PC includes a set of virtual hardware devices, mimicking the configuration of a typical PC. B-HAVE is known to be associated with malware. A program may be deemed to be malicious if it attempts to modify certain files, or a known product of a known virus. When Attempting to use a non-trusted program, B-HAVE delays the launching up to the program’s behavior and characteristics are Analyzed and cataloged in the virtual environment. If no malicious actions are detected, B-HAVE starts the program normally; if a suspect conduct is present, B-HAVE automatically quarantines or deletes the application.
