Flame may be the most powerful computer virus in history, and a nation-state is most likely to blame for unleashing it on the World Wide Web.Kaspersky's chief malware expert Vitaly Kamlyuk shared with RT the ins and outs of Stuxnet on steroids. 
Each of these State created Virus's target the Windows Operating System and very specific security exploits in that OS which again points to the same Virus team that created Stuxnet, Duqu previously.
Powerful "Flame" cyber weapon found in Iran and is now spreading globally hijacking and compromising scores of applications and focusing on the exact same areas exploited by Stuxnet and Duqu strongly pointing to the same exact Israeli/USA virus programmers created the Flame Virus. 
What I find very telling about this 3rd. State Created Virus aimed at Iran is that ONLY the Russian cyber security firm of Kaspersky Lab openly blew the whistle on this latest global danger. I have no doubt the USA anti-virus firms knew about the Flame Virus but were under the NSA machine-gun to not disclose anything relevant about it.
It appears Kaspersky Lab has been able to decompile portions of the Flame Virus and have commented on it's enormous size and scope of operations which Kaspersky Lab is still determining and testing. Sadly, there certainly appears to be a very active censorship on USA based anti-virus firms in reporting on the State created virus's produced to specifically target Iran's computers but without fail have globally infected individual and business computers causing problems, damage and costing untold millions to disinfect and try to repair.
Kaspersky Lab is also researching a vicious Virus which also appears to be State created and targeted at Iran which deliberately erases information on the target computers.
Israeli Deputy Prime Minister Moshe Ya'alon has strongly hinted that Israel was involved in creating the computer virus Flame -- a new Stuxnet-like espionage malware -- to sabotage Iran’s nuclear plans. 
What is truly disappointing is the impression of Israel's officials entirely ignoring International Laws, Treatys, Ethics and Morals involved in unleashing computer virus's on global citizens revealed by this snippit from the same Israeli Deputy Prime Minister:
Speaking in an interview with Israel’s Army Radio on Tuesday, Ya'alon expressed support for the creation of the virus and similar tools, saying it "opens up all kinds of possibilities.” 
While many USA,Global business's have contracts with anti-virus firms to cleanse their servers and their workstations from virus's and worms which were infected by the Flame Virus, Stuxnet and Duqu ALL directly appear to come from the same source with many pointing their fingers directly at the Israeli Government and USA as the virus programmers.
Was flame virus that invaded Iran's computer networks made in USA by the National Security Agency? 
As the United Nations and Iran warn that the newly discovered flame computer virus may be the most potent weapon of its kind, U.S. computer security experts tell NBC News that the virus bears the hallmarks of a U.S. cyber espionage operation, specifically that of the super-secret National Security Agency. 
The article referenced in  alleges the depraved, enormous Flame Virus is 'intended to gather intelligence not destroy equipment or data as was the case with Stuxnet (and Duqu) Virus's.
The only anti-virus firm (Russian led Kaspersky Labs) actually commenting on the workings of the Flame Virus are certainly not spewing this very large Virus is not destroying data. Data destruction allegedly by this virus was the very reason the UN dept. tipped off that Moscow firm to investigate it. It could take months before that security firm discovers and briefs the public on more of the inner workings of the Flame Virus.
Still quite a few USA Business's and of course individuals DO NOT have a contract with a anti-virus firm forcing those business's and individuals to pay to have the Flame Virus, Stuxnet and Duqu cleaned off of their servers and systems and attempt to repair the security related damage those virus's and trojans created out of their own pockets.
I suggest all global business's and individuals forming the latter category of having to individually pay to cleanse and repair their computers from the Flame Virus, Stuxnet and Duqu virus/worm infections to enter a global class action lawsuit against Israel and against the United States Government with punitive damages so high they'll not chose to infect global business and individual computers again.
In regards to infecting USA/Western Computers, yes it is alleged that Israel/USA designed and infected Iran's computer sites with Stuxnet then Duqu and now the Flame Virus however that infection quickly spread globally infecting scores of US Business computers and servers also. USA anti-virus firms appear to be under the NSA machine-guns to not disclose the exact numbers (thousands) nor the amount of reported monetary damage (millions) to the public nor to investigative reporters.
