Mark Allan has updated the free ClamXav virus scanner to version 2.5 with improved stability, several new features, and support for OS X 10.9 Mavericks. The update adds the capability to return files to their original location if they’ve been quarantined or put in the Trash, enables you to pause and resume scans, and prevents the automatic movement of files when scanning email in Apple Mail with the quarantine setting turned on. (These three additions are not available with the Sentry hard drive monitoring tool.) The release also adds Reveal in Finder to the source list, provides “more useful” summary text, adds an option to animate the Dock icon while scanning, avoids a crash if the ClamAV engine isn’t found, and corrects the French localization. Note that as of this writing, the Mac App Store version of ClamXav is stalled at version 2.3.6. (Free, 20.5 MB, release notes)
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
