Within days of the original ILOVEYOU virus infection that took place two years ago, some 40 ILOVEYOU variants circulated on the Internet, now Klez copycats are doing the same.
Virus writers have published what are thought to be the first examples of malicious code targeting an expected feature of Microsoft's Windows Vista operating system, around a week after the first beta of the next-generation operating system was released.
