Spyfalcon removal problems

[Viral]

My friends pc has Spyfalcon on it and he tried to remove it with Windows Defender which seems to have worked but now he gets a notepad message opening everytime he starts up his pc which states,
[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787

Is this because he is missing this .dll?
How can he fix it?
