The purpose of “Silent Runners” is to identify the programs that start up with Windows.
It was first made available to members of the NTBugTraq mailing list in a post on 12 May 2004. The first version posted was actually revision 10. An updated version is available for download here. The revision history is found in comments at the bottom of the script file. Old versions are archived here.
“Silent Runners” is not an anti-virus, an anti-trojan, or a spyware scanner. It only pinpoints how programs start up — it does not scan the system to identify every trace of malware. The text file it creates can be removed for study or stored as a benchmark.
