Somehow I got that new Worm, Sobig f@mm. Does anyone know how to get rid of it?

Here is what I have tried:

First I tried Norton Virus scanner. It failed to remove it, although Norton has been updated completely.

I then tried the online scan from Trend Micro, otherwise known as PCillin. It detected it but could not remove it because it said the file is in use and can not be deleted.

Then I tried the stinger program from mcaffee but it sees the virus but can not delete it. Again, something about the file can not be deleted because it is in use.

I also updated windows.

This worm is embedded in the C:/_restore/temp files and although I have disabled system restore it still says (any virus program) that it IS in use and can not be deleted.

How do i remove the damn worm?

Do I have to reformat and reinstall?

Thanks from Kona!
