I've been hearing about this Flame Virus that has been suspected to have been developed by a Government targeting Iran. I'm well aware of countries that have the most to gain by unleashing such a virus on Iran so lets not turn this into a political discussion. I don't want the thread to be closed. Kaspersky said they first discovered the virus back in 2010. Has any variants been discovered of this extremely powerful virus? How is the payload typically delivered? What type of OS's are affected by this virus?
