TGCMD.EXE is spyware originally created by Tioga/Support.com. If you're an @Home subscriber, this was probably installed with your Comcast @home software. If you own a Sony Vaio system, it was probably factory installed along with the Sony Support software.
This program collects data on the programs that you use and websites you browse. It is unclear if anything is being done with the data. This program and the companion file TGKILL.EXE can be safely uninstalled from the Start menu > Settings > Control Panel > Add/remove programs. Remove either "Comcast Support Software" or "Sony Vaio Support" depending upon which appears.
This program may also appear with the following switches depending upon how it was installed: /server /nosystray /deaf /startupmonitor
