Process Blocker is a simple tool, designed to help system administrators block the execution of certain programs on a workstation. It can be used to automatically terminate instant messengers, games, file sharing apps or any other process you want to block. Simply add the processes you want to clock to a list and the program will automatically block them whenever they are detected running. Process Blocker automatically generates a CRC signature for each executable you add and gives you the option to block the process based on the CRC - this allows you to block the process even if the file has been renamed.Process Blocker is free unless you require extended functionality such as whitelisting or user-specific rules.
