Norton Antivirus Disabled by Trojan?

Hi. I use Windows XP. My computer got hit yesterday with the Download.Trojan. I had several Internet Explorer 6 windows open so I'm not sure which site it came from. But it must have been one site I hadn't visited in about a year or so. The trojan was trying to download something. I refused and then the Norton Antivirus 2004 warnings started appearing. It could not access some files. The PC crashed and I rebooted. It froze from startup and complained about a system failure. I rebooted again and same thing happened.
A few hours later I turned it on again. Windows loaded. Ran Norton and it found nothing but the usual spyware. No trojan.
Today I looked at the log and found the trojan's name. I followed the instructions in the Symantec page to delete all offline content in IE. I had seen in Norton's log that all the trojan files were in my user profile only. So I cleared it.
The only problem I notice now is Norton is always disabled after each boot. Meaning I restart Windows after making sure Norton is enabled, yet when it starts up, the program's icon in the system tray has an X mark. Is the trojan disabling it? Or was it damaged when it tried to intercept the trojan?
How can I be sure I've gotten rid of this thing?
Also, there's something wrong with my Samsung DVD drive. It renders all my CD-RWs unrewritable after one use. It reports that they are all full. This has happened 3 times today. Did it get infected with a virus?
Thanks for your help!
