Mark Allan has released ClamXav 2.6, which updates the ClamAV engine to version 0.98. ClamXav, Sentry, and the ClamAV engine are now 32/64-bit, and ClamXav now requires Mac OS X 10.6 Snow Leopard and an Intel processor. The release also adds compatibility with Notification Center on 10.8 Mountain Lion for ClamXav (but not Sentry), fixes issues with unnecessary reporting of quarantine folders and updated virus definitions, adds a timestamp to logs of scheduled scans, and makes improvements to the French, Italian, and Czech localizations. Shortly after the 2.6 release, 2.6.1 was released with a fix for 32-bit machines running Snow Leopard. (Free, 19.8 MB, release notes)
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
