Macs have largely been spared the virus and trojan issues that have crippled Windows PCs for years, but Flashback malware is now making rounds—and the news. Statistically, you’re probably not in any danger, but it’s worth checking your Macs to confirm you’re not part of the 1% that’s been infected. The easiest tool we’ve seen is developer Juan Leon’s Flashback Checker (Free), which handles the dirty work for you.
Just click the “Check for Flashback Infection” button and the app will run the background OS X Terminal commands, letting you know within a second or two whether or not your computer has been hit. If so, it’ll link you to F-Secure’s instructions for removing the infection, which isn’t too tough either. Apple’s working on official solutions, but until then, this is a good way to figure out if you have anything to be concerned about.
