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)
Hide TextExpander in the Dock
If you don't want to see TextExpander's icon in the Dock and the application switcher, you can remove it. Just open TextExpander > Preferences > Appearance, and select Hide TextExpander Icon in Dock. You'll still be able to access TextExpander from its menubar icon.
