Windows "Security Threat"

Open Notepad

Enter the text. All one line
x=msgbox("This application will not be opened due to security threats", Close, "Warning")

Save as anything ending in .bat but all 1 word
Save it in all files

Make a shortcut for it, saving it as Internet - Shortcut
The shortcut is important

Right click, and left click properties
Click change icon, under shortcut
Select the internet explorer icon
Click ok, and then apply
Then double click, "Internet Shortcut"

Try putting it on other computers via flash drive, not the funniest, unless you move all other internet access out of sight
