This just in from David Passell, "Look what the regularly scheduled MacScan found this morning after yesterday's Google Chrome testing. Coincidence? Maybe not since the file path leads to Firefox/Profiles. Needless to say I will isolate (remove) it. (I'll look at that file first)." See http://macscan.securemac.com/ for Free trial.
And this from Apple, "will find, isolate, and remove spyware, keystroke loggers, and trojan horses as well as detect whether remote administration applications have been installed on a computer." Free download of MacScan 2.7 here. (Double click to enlarge screen shot.)
