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)
Expand Finder Columns Quickly
Column view in the Finder is great for navigating through your disk's hierarchy, but the columns often aren't wide enough to show the full names of all the files. To expand a column to a width that will show all file names in their entirety, double-click the handle that you would normally drag to expand or shrink the column. To expand all the visible columns to that width, Option-double-click the handle.
