AppleScript "Fake" Virus Question

[metalman1253]

I am making a fake virus for mac using Applescript. Here's what I've got so far. Final Stage.rtfd is this in textedit. I need it to display fullscreen this image.

display dialog "A Virus Has Been Detected" buttons {"Destroy Virus", "Crash CPU (Risky)"} default button 1
if the button returned of the result is "Destroy Virus" then
	tell application "Finder" to sleep
	display dialog "haha"
	say "you cannot destroy me"
	display dialog "trying attempt 2"
	tell application "TextEdit"
		activate
		open "/Users/bbradley/Desktop/Final Stage.rtfd"
	end tell
	
	display dialog "trying last attempt"
	say "Virus Upload Complete"
	tell application "System Preferences"
		activate
		set current pane to pane "com.apple.preference.displays"
	end tell
	
	tell application "System Events"
		tell process "System Preferences"
			tell slider 1 of group 2 of tab group 1 of window 1
				set value to 0.0
			end tell
		end tell
	end tell
	
	tell application "System Preferences" to quit
else
	display dialog "Good Move"
end if
