[DGMLT]

I found a worm on my computer a few months ago and removed (or atleast I thought I did) with the help of this site, but soon after it became clear that there were still problems. This time when I did a Norton scan it showed three Trojan Horses, but could not remove them. They are:
[dtreg.exe] inside of [c:\msdos]
[pv.exe] inside of [c:\msdos]
[serv.exe] inside of [c:\msdos]

Here the HijackThis Log, please let me know what I should do and if there is anything else I should be worried about!
