Please Help Get Rid Of This Virus, HJT Log Attached.

[Sky_Captain]

Could somebody please help me with this one. I have an older version of Norton Anti-virus that has picked up on a virus in my Microsoft FrontPage programme. Only problem is, is that when I run AVG 7.0 the scan always comes up clean saying there is no virus.
The Norton Advisory message states:
Object Name: C;\WINDOWS\default.css
Virus Name: Trojan.Bootconf
Action Taken: Unable to Repair this file

I click ok and then it says:
Action Taken: Access to the file was denied

Its a pain in the ass and has me a little worried. One other query for those in the know, each time I run Spybot Search and Destroy, I always have a possible hijacker which the programme can fix each time, but I also have a Cool Web Search problem that it refuses to fix, and always asks do I want to run the programme again after a re-start? Although I run CWShredder and I find nothing, the system is clean. Anybody have any thoughts?

As promised, one HJT Report, hopefully it sheds some light on my problems:
