I haven’t consider viruses a significant threat on Mac OS X. While vulnerabilities exist, they’re so rare I figure don’t have to worry. Yet.
Then I read that Louis Gray, a well-respected blogger, got a Mac OS X trojan. It hijacked his computer’s DNS settings, replacing the banner ads appearing on his webpages with ads for erectile dysfunction pills.
So. Time to install some anti-virus software. I researched, and found only one good, free anti-virus app for OS X: ClamXav. It’s simple and sluggish, but effective. Which is all I need and want.
I’ll post here if I encounter any problems. But this has taught me a lesson: be prepared before trouble hits.
