The best thing to do is to access this forum from another PC and download all the kit recommended. Then copy it onto a disk and run it "locally" on your PC. It won't then require you to connect to the net as this seems to be your biggest issue.

I agree with that,

Seeing as though your Norton is taking flack, might be worth downloading Stinger. (worth a shot)

Steps:

Obtain McAfee's virus and worm removal tool, Stinger: http://vil.nai.com/vil/stinger/

1) If you are using WinME or WinXP, disable System Restore
http://vil.nai.com/vil/SystemHelpDo...eSysRestore.htm
2) Reboot your PC into Safe Mode and shutdown as many applications as possible
3) Using McAfee Stinger, perform a Full Scan of your platform and clean/delete any
infectors found
4) Restart your PC and perform a "final" Full Scan of your platform
5) If you are using WinME or WinXP, Re-enable System Restore and re-apply any
System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
6) Reboot your PC.
7) If you are using WinME or WinXP, create a new Restore point
