Despite Apple's release of numerous Java patches and an uninstaller tool, some 140,000 Macs worldwide are still affected by the Flashback trojan that was at one point present on 600,000 machines.



From Apple Insider:

Although malware-affected Macs are on the decline, the numbers are at a point much higher than forecasted by software maker Symantec, according to a Tuesday post on the company's blog.

The security firm guessed that the number of affected machines would have dropped precipitously by now given that Apple and third-party vendors released their respective Flashback-neutralizing programs last week. The Mac maker even rolled out a removal tool for those Mac users who don't have Java installed, and thus may be harboring a dormant version of the malware.
