Can't remove Trojan Virus- Help!

[songwritingguy]

Greetings.
I've just installed Norton Antivirus 2005 on my new custom PC. Apparently though, I downloaded a virus before I had this software. Norton keeps finding the virus but cannot delete it. I tried the manual process - went to msconfig, safemode, explored out to the infected file and tried to delete it, and no such luck.

How do I get rid of this thing? Norton keeps giving me the message that it exists. It's a 'download.trojan', and it's in:
C:\WINDOWS\SYSTEM32\KE32PC8GNDE.dll
I have no idea how to proceed. Appreciate the help.....

Here's my system info:
Windows XP Home
AMD 64 3000
1 Gig Ram
60 Gig HD
160 Gig HD

OK, I was an NT admin for years, so keep that in mind. Want my advice? REFORMAT. Once a trojan has taken hold, you've essentially been hacked. You're had, pwn3d, your system is somebody else's property. If the trojan writer was intelligent, it's already embedded itself deep in the roots of Windows. Time to reformat...
