Apple responded fairly quickly to news that more than 600,000 Mac computers were infected with a trojan virus called “Flashback.” One week after the massive botnet was discovered, Apple issued an update fixing the Java vulnerability that allowed Flashback to infect the machines, as well as a removal tool for affected machines. Despite the company’s efforts, Symantec stated on Tuesday evening that approximately 140,000 OS X PCs were still infected with the virus at that time. “The statistics from our sinkhole are showing declining numbers on a daily basis,” the company wrote on its blog. “However, we had originally believed that we would have seen a greater decline in infections at this point in time, but this has proven not to be the case. Currently, it appears that the number of infected computers has tapered off, but remains around the 140,000 mark.” Symantec offers its own Flashback removal tool separate from the one Apple made available in a system update on April 12th.
