The Conficker worm or Conficker virus (also known as Downadup or W32/Downadup), which has been in the news a lot lately, is currently estimated to have infected more than 9 million Windows computers the world over, and continues to spread at an alarming rate. With a $250,000 bounty on its head offered by Microsoft, and set to activate on April 1st, nobody yet knows what the millions of PCs infected by the Conficker worm will be ordered to do, but it’s a sure bet that if and when it happens, it will be nasty. Fortunately there are ways to combat it and even a free Conficker removal tool.

A new computer worm called Downadup – also known as the Conficker worm – is spreading like wildfire across personal computers, even though it has only been on the scene for a relatively short time. First spotted just weeks ago, in November, the Downadup worm is estimated to already be resident on at least 3 1/2 million PCs.
