Cytron Removal Instructions:

First deregister the Cytron BHO. Open a DOS command prompt (Start->Programs->Accessories) and enter the following commands:

cd "%WinDir%\System"
regsvr32 /u "%WinDir%\Downloaded Program Files\potd.dll"
(Change potd.dll to sec.dll if you have Cytron/sec variant.)

You should then be able to delete the 'TargetingSource' entry in Downloaded Program Files (in the Windows folder), and the registry key HKEY_CURRENT_USER\Software\POTD (Start->Run->regedit).
