When I attempted to obfuscate ~ compile an AutoIt script on my home computer - my McAfee virus detector went off. Don't know whether this is because the obfuscation is looked at as the virus signature or because there's actually a virus. To find out more I uninstalled (versoin dated from 7/2009) & download installed latest version of AutoIt and SciTE and tried again. Same behavior. No obfuscation until I learn more.
