Previous instructions for finding out whether your Mac is infected with Flashback have required complex command line steps, and checking for multiple variants in order to do a complete check, at least for those who don't have an AV that they trust completely installed.

There is now a simple program to check whether your Mac is infected with Flashback.

An Article at PC Advisor tells you a little about the program and where to get it.

Initial reports on Flashback came almost exclusively from a single source. The most recent report is that a second source has confirmed that approximately 2% of all Mac computers are infected, for a total of "more than 600,000" individual machines. One report is at another PCAdvisor article.
