After installing Internet Explorer 8 and rebooting on Sunday, I noticed during the day on Monday that ClamWin, Spybot Search & Destroy, and at least one other application were partially deleted.

ClamWin (after reinstallation) found two infections in files under C:\Windows\System32:
JLSKON.SYS had Trojan.Small-5240
Various other randomly-named *.DLL and *.DL_ files had Trojan.Small-4845

Windows Defender (with current signatures) and Microsoft Malicious Software Removal Tool (manually run) found nothing amiss.

DDS tool result is attached. The system is now disconnected from any network to prevent further downloads from the mothership (wherever that might be).

Any suggestions on appropriate cleaning tools would be appreciated.

Thanks,
Scott

The problem was "resolved" by reinstalling the affected machine from scratch.
