Abstract: A system and method for reducing false positive indications of pestware on a protected computer is disclosed. In one variation, the method includes tracking activities of a user at the protected computer, monitoring events at the protected computer, identifying events that are potentially indicative of pestware, comparing at least one of the events with at least one of the activities of the user and initiating, in response to the comparing indicating the activities of the user are unconnected with the events, a user prompt that informs the user about the events to enable the user to make a decision relative to managing the events.

Abstract: Systems and methods for managing pestware are described. One system includes a pestware shield configured to detect pestware activity on a protected computer; a heuristics engine configured to identify repeat pestware activity; a drive scan module configured to scan files stored on the storage device and to identify pestware in the scanned files; a program memory scan module configured to scan programs running in the program memory of the protected computer and to identify pestware in the scanned programs; a registry scan module configured to identify any attempts to change data in the registry file; and a quarantine module configured to quarantine the pestware identified by either the drive scan module or the program memory module.

Abstract: Systems for preventing pestware activity are described. One embodiment a heuristic engine configured to identify repeat pestware activity and configured to block the repeat pestware activity; an operating system pestware shield in communication with the heuristic engine, the operating system pestware shield configured to detect pestware activity and report the pestware activity to the heuristic engine; and a browser pestware shield in communication with the heuristic engine, the browser pestware shield configured to detect pestware activity and report the pestware activity to the heuristic engine.
