Downandup/Conficker worm infects 9 million PCs 2009-01-21 - [tech.yahoo.com...]
The numbers of infected machines are increasing...
How bad has it gotten? Estimates range from 3.5 million infected in the first four days after it began spreading to 9 million impacted... and getting worse. By now I figure the numbers could top 15 or 20 million.
