Mark Allan has released ClamXav 2.3.2, which fixes an issue that prevented ClamXav Sentry from launching at login when running OS X 10.8 Mountain Lion. The update also fixes an issue where ClamXav Sentry wasn’t able to communicate with the clamd background scanning daemon, plus Engine Uninstaller issues with Gatekeeper. The release’s one addition enables you to open the Sentry log from within ClamXav (and vice versa) by holding down the Option key. (Free, 16.9 MB, release notes)
Fun Way to Send Attachments in Mail
If you're working in a file that you want to attach to a message in Apple Mail, you can transfer the file to Mail easily: From the title bar of the file's window, drag the little proxy icon to Mail's icon on the Dock. Your Mac will make Mail the active application and open a new outgoing message, with the file attached.
(If your icon won't drag, the file probably isn't saved.)
