Auto-Protect detecting a trojan horse

I get this message after norton has performed an idol scan, "Auto-protect has detected a trojan horse." When i go into details to check to see what this message is referring to it says that severity: high, activity: Auto-protect has detected a trojan horse, date:5/13/2009, Status: Blocked, Recommended Action: Resolved-no action.

 

Should i be satisfied with what i have listed above or is there still a trojan threat on my computer? I look forward to getting an answer on this matter.
