Hey Jim
Try this, not too sure if it works 100%

Unregister DLLs:

Unregister these DLLs with Regsvr32, then reboot:
mydailyhoroscope17307.dll

Remove Files:

Remove these files (if present) with Windows Explorer:
mydailyhoroscope17307.dll

Also might be worth downloading AVG and trying to scan it with that.

Have you tried booting your machine into SafeMode and running the viruscan from there, this normally fixes the problem when anti-virus stuff cant "disinfect or delete files"

Also might be worth posting your HiJack list for us to check.

Unfortunately ... in safe mode I have no access to the Fsecure program.. But I tried renaming a tmp folder and putting the files in there.. but no luck..can't move files .. or rename them.

Hi Jim.

I have had the.dropper "trojan" in the past and I got rid of it by running Ad-Aware. It's usually associated with mp3 sites.

Could you post a HijackThis list, will make it easier to see the problem

Otherwise
Try boot into safemode again, this time open the registry. (START --- RUN --- and type regedit)

Look in the following folder
HKEY_LOCAL_MACHINE --> SOFTWARE --> MICROSOFT --> WINDOWS --> CURRENTVERSION--> RUN

Look for anything strange e.g. anything with these names:
  • saie321
  • in10b6s
  • mb

Also run a search for these files:

? C:\WINNT\system32\in10b6s.dll
? C:\WINNT\system32\MB.dll
? C:\WINNT\system32\saie321.dll

Delete the files once found. (Windows doesn't need them)

Could be worth checking this website out:
