Kurt,
Please see my reply to your questions below:
Kurt: What action is SAV taking on the file when detected? This should be noted in the client's risk log and/or scan log.
Andy: On different PCs, SAV is taking either of the following actions: Quarantined, Left Alone or Deleted. However, the file path is stated as "Unavailable".
Kurt: Is Auto-Protect detecting the file on the PC's, or is it only detected during a system scan?
Andy: Symantec is detecting the file on "Start-up" scans or during "Manual Scans".
Kurt: When running the full scan on the server hosting the PC's home folders, is the file present in the directory before the scan is launched?
Andy: When running the full scan, the file is present in the directory before the scan is launched. However, the scan did not picks up the infected AutoRun.inf files. Only the PCs do.
