Clean Slate security goes beyond just clearing unwanted changes. You can also block programs from running. Clean Slate reads and lists all the programs in your start menu. While in the Clean Slate configuration screen, simply select the programs you want blocked. Once configured, the programs can not be accessed. Not only will Clean Slate block the execution of any presently installed programs but also unknown programs from the Internet and removable media (USB drives, CD ROM, network shares, floppy disks, etc.).
