Mydoom
The virus was found to be a threat on January 26, 2004. The virus quickly spread and proved a threat to the SCO group. To try and get the public to catch the maker of the virus, the SCO group offered $250,000 U.S. dollars as a reward for catching the creator. Another type of the virus, Mydoom.B was found on January 28. Because it was made to attack the Microsoft web site, Microsoft offered a $250,000 U.S. dollar reward if the maker of the virus was caught. This was the third time Microsoft offered a reward for catching a virus creator.
