ClamXav Sentry is not available in the Mac App Store version of ClamXav.
ClamXav Sentry provides the ability to watch folders for changes to their contents. As soon as a file or folder is added to one of the watched folders, it is scanned by ClamXav. If the new addition is clean, no further action is required on your part. On the other hand, if it is infected, a warning message is displayed immediately alerting you to the fact and allowing you to decide which course of action to take.
ClamXav Sentry also offers you a short cut for updating the virus defintions which can be done directly from the menu without needing to launch ClamXav itself.
When active and watching folders, ClamXav Sentry appears as an icon in the menu bar - five vertical bars behind the silhouette of a folder. All actions related to watching folders are performed via this menu icon.
The menu item changes to indicate its state as follows:
No folders to watch or watching has been stopped temporarily
Watching folders for new additions - scan not currently in progress
Actively scanning new additions to one or more of the watched folders
Sentry is updating virus definitions
Before you can actually make use of this feature, you must specify which folders you wish ClamXav Sentry to watch. This is done by choosing the Add/Remove Folders option from the ClamXav Sentry menu.
Upon doing so, ClamXav will start up and open the preferences at the Folder Sentry panel. Please consult the ClamXav Preferences documentation for complete information on how to specify which folders to watch.
When ClamXav Sentry is launched it will automatically start watching the folders you specified in the preferences. If you have not yet done so, the menu will be grey with only the outline of a folder as there is nothing to watch. You will also be alerted to the fact by a dialog box which offers the option of quitting ClamXav Sentry or opening ClamXav's preferences.
Should you wish to suspend ClamXav Sentry's actions temporarily, you can choose Stop Watching from the menu. Watching can be started again subsequently by choosing the appropriate menu item.
If a scan is taking significantly longer than you expect it should, or if you have just inserted a large disk or mounted a large network volume, then you may abort the scan to prevent ClamXav from eating up useful processor cycles.
A word of warning: When you choose to abort a scan, ALL currently running scans are aborted - this will not affect any scans which may be in progress within the main ClamXav application.
Quitting ClamXav Sentry (an option which is not available during a scan) will automatically stop folders from being watched. From then on, new additions to the specified folders will not be scanned unless you explicitly do so from within ClamXav.
