Centurion Technologies, a producer of hard-drive and configuration-protection solutions, featured its CompuGuard CornerStone software. CornerStone is meant to maintain a computer’s critical configuration settings. The company says CornerStone protects against configuration setting changes by making them disappear upon reboot, enabling users to experiment without doing harm. The process also eliminates a number of maintenance issues, according to the company. It reportedly protects against viruses and enables web surfing that is safe from spyware and other malware designed to intrude upon user privacy and steal information. Centurion says the application takes up only a small amount of hard-drive space and improves workstation performance in the process.
