Norton 2009 Not scanning Properly

Hi There

 

I've done a few scans of my system and attached them. Hopefully there'll help diagnose my problem.

My problem is when I try and do a scan Norton says: "Scanning start up files....", but it doesn't show the name of the files being scanned or the number of files scanned. Also Norton pops up a box saying Trojan Horse detected. What surprises me is that if Norton knows the files there then why doesn't it given the name and then delete it.

Thanks for your help. I hope that I've posted this to the right place?

Regards
