Computer viruses have come a long way since the early days of the personal computer, when hackers bragging rights for adolescents, developed the creation of malicious software that compete for damage or random chaos. Now the pirates have moved their professional ambitions have become, but fans working in the basement of her parents, malware authors are often part of a gang underworld, or directly to a foreign government or an intelligence agency. Because the inserts are developed, they also have the potential to damage and destruction caused by malware.
1) Stuxnet (2009-2010) The arrival of the Stuxnet was like a bad comic book come to life: he had developed the first computer virus to cause damage in the real world, as opposed to the virtual world.

But the real secret of Conficker is still infecting many computers that we do not know what to do: botnet army has never been used for certain purposes, to the attention of everyone. Real purpose of the Conficker still confused security experts.
3) agent.btz (2008) This piece of malware is claim to fame is that temporarily forced the Pentagon to spend a blanket ban on USB drives and even helped.
