have path of trojan, per NIS, but can't find file!

I ran a full system scan, in safemode, and Norton found me 3 trojan files it said it could not remove.  I followed the path of each file, and found that near the end of the path of each file, the next directory listed didn't exist.. so I couldn't find the files to remove them.

 

Any advice?  I can post the path of one of the files if necessary.

 

Thanks!
