If so, it sounds as though your antivirus/antispyware has removed the malware file(s) but not the reference that loads it/them.
Remove the entries by clicking Start > Run, type regedit, press Enter and navigate to registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
In the right pane look for the two dll names and if they are there, right-click them and select Delete.
Also, look in this key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
