Most of the time this may be occured due to removal of malware/adware by an antivirus but not removing startup entry .. (Yet, Scanning using malwarebyte is a good idea http://www.malwarebytes.org/free/ )

But you may need to remove it through start up or other means.. 

(1)  if there is anything related to the .dll u you have described here , at system tray start up disable it ..

or 

try to use "Autoruns for Windows"  and check whether there is a startup entry related to the .dll u you have described and if so remove it..

 If you look it, it should be under this  in yellow colour 

In case if you can't find it using aforementioned methods, this could be under 

taskschedule===>task scheduler library . If found delete the entry related to ftphost.dll from task scheduler library

or 

you may use regedit.. Press windows R key and type regedit and click ok.. (before editing export the key your are going to edit or delete)
then navigate to these paths.. 

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]

then look for .dill file you have described here and delete that key.. REBOOT
