The previous update shipped in August of last year and, sometime in the interim, v2.2.3 slipped through the cracks or a wormhole perhaps. Wherever it went, there is a fresh version for the rest of us that includes v0.97.4 of the open source Clam engine.

One of the few annoyances presented by this AV scanner has been obviated. ClamXav 2.2.4 (version history) allows the user to exclude previously identified infected files, such phishing emails — cool.

Features and fixes in this release:

• Updated ClamAV engine to 0.97.4
• Added ability to exclude “infected” files from future scans – useful to ignore false-positives
• ClamXav Sentry will now check for updates on launch if set in ClamXav main preferences
• Fixed a crash which could occurr if the designated Quarantine folder didn’t exist
• Fixed bug which could cause items not to be scanned in rare circumstances
• Fixed minor errors in German localization
• Updated version of Growl bundled with ClamXav Sentry
• Improved stability during updates
• Requires OS X 10.5 or later, Lion compatible

Trust with verification. I know my Mac is Trojan free and that certainty takes almost zero effort.

ClamXav is available on the Mac App Store (free), as well as direct from the developer.
