Deus Ex Alpha

Hello!!! I have a problem I get an error like this vbc30201 (Expression expected)

My Sub is :

Private Sub Button1_Click(ByVal sender As SYSTEM.Object, ByVal e As SYSTEM.EventArgs) Handles Button1.Click
Kill(Process.ReferenceEquals(My.Computer.FileSystem.FileExists("C:\WINDOWS\notepad.exe"), as object))
End Sub

Error is at ...("C:\WINDOWS\notepad.exe"), as object

Can someone tell me how I can resolve that error?

(NOTE: sorry for my language, not so good lol)
