Before I do anything, I think it would be helpful if I provide some additional information (see below).
Then tell us what version of OS X you are running plus what Mac you are using!
I'm on an iMac (27", 3.2 GHz Core i3, 4GB RAM) with a 1TB HDD, running OS X (10.6.8). (I'd like to include this info in a signature, but can't figure out how to do that.)
OK. Here's the additional info: I was rather overdue for a Software Update — I had been putting it off because I was having bizarre operational problems that resulted in difficulty booting/rebooting (required for the Update) and I absolutely needed to be online during this period. So I let the machine run 24X7. I realized it'd get to the point that I couldn't put it off any longer, because the operational problems were getting worse. Last week "Catch-22" finally caught up with me: The machine froze, and I had to shutdown and reboot via the power button. Once that happened, I did the Update, and was notified that the Flashback trojan was found — and deleted — during the Update. The operational problems have since abated quite a lot, and I've rebooted several times since then with no problem (though I'm still reluctant to shut the Mac down at the end of the day). It struck me that the "apple-scc-20120126-112417" file might be something that the trojan installed back in January (the "20120126" seemed to suggest Jan 26) and remained on my machine through my previous Update (which was in February). But I simply don't know. I also don't know why I can't find it via the Finder.
Is any of this helpful? Does it suggest a different/modified course of action?
