Process Blocker is a simple utility that lets you block access to specific programs or processes. If you need to keep children or employees off of chat, solitaire, and other time-wasters, this is an easy solution. It's also an effective way to block some types of malware while you figure out a more permanent way of dealing with the attack.
Process Blocker has a simple interface that's easy to navigate. The blocked applications list displays a list of everything that the program has been set to disable; to add to the list, click the Add button and then simply browse to the executable that you want to block. The program can also optionally block the CRC so that the process will continue to be blocked even if the name of the executable is changed.
Process Blocker also has an information and statistics screen that displays the number of times an application has been blocked, and there's an option to disable a system tray notification that pops up when Process Blocker blocks something. It's important to note that Process Blocker itself doesn't come with password protection or any other means of controlling access to it, and it's easy to simply uninstall it; users will need to run it as an administrator in order to prevent unauthorized access.
The program comes with a built-in Help file that provides brief instructions for installing and using Process Blocker, but the whole thing is pretty straightforward. If you need an easy way to prevent certain programs from being launched, Process Blocker is about as easy as it gets.
