Computer security firms rush to put out Flame

Flame, one of the most complex computer viruses ever discovered, has been detected in China and could potentially cause widespread damage - including information leakage - to company and government networks as well as individual computers, experts warned.

"According to our analysis, the virus was designed mainly to target governments, firms, schools and scientific institutions," said Liu Siyu, director of the research and development section of Rising International Software, a Chinese Internet security company.

"However, the technology it used could be adopted by other lower-level Trojan viruses and cause damage to the networks we use in our daily lives," he said.
