Actually, it wasn’t all that interesting, and I run Mac, Linux, and Windows machines. If you read the article closely, you surely noticed only 2.7% of Macs were infected with Mac OS malware. That seems pretty low to me. The 1 in 5 figure was for Macs with Windows software, i.e. Boot Camp. Based on my experiences, Mac OS is by far a better operating system as far as malware. That’s not saying Windows and Linux don’t have their own advantages. They do.
But we were told Macs can’t get malware.
With such a small footprint this is just the beginning. I’ve said all along Macs enjoyed good security with a small user base (relative). However, now that it’s getting a larger user base we’ll see more and more attacks. And recent issues show that Apple isn’t ready to handle it.
That's not even "infected"... just present. They are all trojans. They may be sitting in an unopened email... un-executed. If the the Mac is a newer Mac, running Snow Leopard or Lion, ALL of these Trojans would be prevented from running.
The OTHER dirty secret of Sophos' AV, is that it TURNS OFF Apple's own anti-Trojan software so that Sophos' AV can even see the downloads as they occur... otherwise the system prevents the download from occurring! If you were running the System Software as intended, the AV from Sophos would not even see the vast majority of the Mac Trojans it is reporting.
