* Kaspersky warns nation's cyber warfare can get out of hand
* Says governments must cooperate and software redesigned

TEL AVIV, June 6 (Reuters) - Eugene Kaspersky, whose lab discovered the Flame virus that has attacked computers in Iran and elsewhere in the Middle East, said on Wednesday only a global effort could stop a new era of "cyber terrorism".
"It's not cyber war, it's cyber terrorism and I'm afraid it's just the beginning of the game ... I'm afraid it will be the end of the world as we know it," Kaspersky told reporters at a cyber security conference in Tel Aviv.
"I'm scared, believe me," he said.
News of the Flame virus surfaced last week. Researchers said technical evidence suggests it was built for the same nation or nations that commissioned the Stuxnet worm that attacked Iran's nuclear programme in 2010.
In recent months U.S. officials have become more open about the work of the United States and Israel on Stuxnet, which targeted Iran's Natanz nuclear enrichment facility.
The West suspects Iran is developing atomic weapons. Tehran denies this and says it is enriching uranium only for civilian use.
Security experts say Flame is one of the most sophisticated pieces of malicious software so far discovered. They are still investigating the virus, which they believe was released specifically to infect computers in Iran and across the Middle East.
Kaspersky named the United States, Britain, Israel, China, Russia and possibly India, Japan and Romania as countries with the ability to develop such software, but stopped short of saying which nation he thought was behind Flame.
When asked whether Israel was part of the solution or part of the problem regarding cyber war, Kaspersky said: "Both."
"Flame is extremely complicated but I think many countries can do the same or very similar, even countries that don't have enough of the expertise at the moment. They can employ engineers or kidnap them, or employ 'hacktivists'," he said.
"These ideas are spreading too fast," Kaspersky later said, "That cyber boomerang may get back to you."
Kaspersky said governments must cooperate to stop such attacks, as they have done with nuclear, biological and chemical weapons. Operating systems must be redesigned, he added.
"Software that manages industrial systems or transportation or power grids or air traffic, they must be based on secure operating systems. Forget about Microsoft, Linux, Unix."
Kaspersky said malware like Flame and Stuxnet have a limited lifetime and that undiscovered viruses could be out there.
"It's quite logical that there are new cyber weapons designed and maybe there are computers which are infected."
At the conference Kaspersky got celebrity treatment, with students huddled around to have their picture taken with him. He spoke alongside Israel Defence Minister Ehud Barak and top security experts from leading hi-tech companies.
Barak said a more comprehensive approach was necessary to deal with cyber threats and it required cooperation on an international level.
"The damage you can save yourself from proper defence may be more than what you achieve through the offensive action, though both aspects exist," Barak said.
