ESET SysInspector is a free, state of the art diagnostic tool for Windows systems. It is also an integral part of ESET Smart Security 4 and ESET NOD32 Antivirus 4. It peers into your operating system and captures details such as running processes, registry content, startup items and network connections. Once a snapshot of the system is made, ESET SysInspector applies heuristics to assign a risk level for each object logged.
