Still Infected After All These Days
On the left is a 3d bar chart of a block of about 65,000 IP addresses at one ISP in India. Each infected host is represented by one column with the height of the column being the number of days the IP address has been on the CBL, list of comprimised host IP addresses.
This level of infestation is by no means unusual or unique - the customers of many ISPs around the world are similarly mass-infected.
We'll add some instructions for checking your computer for infection and cleaning it up shortly.
