No reports in the wild? Consider this a report.

Threat level low? Why does Norton/Symantec rate it as high...once it finally gets a clue? Browser was hijacked, Norton found nothing. It took Spybot S&D to figure it out, then TDSSKiller to find and remove the bootsector infection.

Norton was totally useless and had no idea until *after* tdssKiller went to work on it.

I wonder what Peter thinks of his namesake now?
