Process Blocker

Process Blocker is a neat, simple and small application that does what its title says: it lets you block processes from being executed on a computer.

It has been created specifically with the purpose of being a security project capable of preventing the running of any Windows application, and that's what it flawlessly does. Anyway, Process Blocker is not only reliable, but also very simple and easy-to-use. It doesn't come with a typical interface, just a window where you can add the apps that you want to block and one where you can check a few basic options: enabling tray notifications upon app blocking and enabling logging the blocking activity to a file. If you purchase a license key for the app, you can also use exceptions lists (“whitelisting”) and add apps to the block lists using user and group-specific rules.

As you can see, Process Blocker is so simple that even complete beginners could use it without any problem. It's also suitable for professionals as it allows a lot of flexibility when it comes to the blocking rules, enabling the blocking of applications by wildcard, by user name or group, or even by CRC.

To cut a long story short, Process Blocker is a nice security tool that does a great job at helping you block processes and apps from running on your computer.
