OK, so you might have heard about the latest security threat to the Mac called “iWorm.” There are supposdly thousands of “infected” Macs ready to rain down doom and destruction at the behest of its bot-net wrangler. The good news is: it’s not a “worm” at all in that it can’t autonomously install itself into your computer. It is in fact a “trojan horse”, requiring that you allow it into your Mac most likely by installing a compromised application. For example, it has been detected in pirated copies of popular apps (Office, Photoshop, Parallels) available on bit torrent sites. Another reason to avoid plumbing those murky depths.
It is a variation of an existing trojan already detected by anti-virus software but you can easily check if you have somehow managed to “catch” this malware by a quick Finder check:
- From the Finder’s Go menu choose Computer
- In the Finder window that opens double click your hard drive icon
- In the hard drive contents double click Library
- In the Library folder double click Application Support
- In the Application Support folder look for an item named JavaW
If you find it, you’ve got iWorm. You should be able to remove it via a free anti-virus app like:
NOTE: This is not an endorsement of either app, they just happen to be free options.
Apple has updated their own built-in OS X anti-virus definitions to include this new threat so if your Mac is up to date it should be protected from new instances. If you’ve already been “infected” you’ll probably have to use an anti-virus app to remove it.
