The Mydoom virus (also known as a worm and as Win32.Mydoom.A) was a very damaging computer virus that affected Microsoft Windows-based computers. The worm was spread through mass emailing, disguised as badly sent email. Design and infection
The virus was made to be sent in an email with an attachment that carried the virus. When the attachment was opened, the virus would download itself to the computer. The virus can only affect Windows based computers. The virus came with a package that would spam the SCO Group website.

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.
On February 1, 2004, the virus downed the SCO group site with many denial-of-service attacks. On February 3 the virus attacked the Microsoft site and little damage was caused.

For a period of a few hours mid-day, the worm's rapid spread slows overall internet performance by approximately ten percent and average web page load times by approximately fifty percent. Computer security companies report that Mydoom is responsible for...
