McAfee AVERT Stinger
Stinger is a stand-alone utility used to detect and remove specific viruses.

Stinger utilizes next generation scan engine technology, including process scanning, digitally signed DAT files, and scan performance optimizations.
This version of Stinger includes detection for all known variants, as of February 21, 2005:
