The software name may be small but its funcationalities are not at all. The suite of features covers the protection from various angles - from network security, file and registry protection, application launch control and management through signature based Intrusion detection and Prevention.
Most importantly - these security features are packed into user friendly tools - such as Track'n Reverse tool which allows to erase changes made to the computer by the applications. Whenever you are unsure about the application behavior - just put it into the Track'n Reverse mode knowing that all your files and registry will be protected and the changes including the deletions could be brought back.
