A computer worm that managed to infect a large number of computers. On April 1st, 2009 the Conficker worm will simply start taking more steps to protect itself, in doing so it might infect even more machines. The Conficker worm has created secure infrastructure for cybercrime. The worm allows its creators to remotely install software on infected machines. The worm effectively blocks access to most websites and/or redirects the user to alternate sites who want to send SPAM, steal IDs.
It is recommended that users download patches for Microsoft and their anti virus programs. As usual, users with OSX (MACs) do not have to worry.
The shitstorm as a result of the Conficker virus has caused Microsoft to do nothing to make their OS better, but instead they offered a measly $250,000 for anyone with information on the authors of the malicious code.
