The user interface is quite straightforward and provides access to all available features in a streamlined fashion, giving you access to the toolbar, source list, infection list, console, and status area quite easily.īefore scanning for viruses on your Mac, users are strongly advised to update their virus definitions from ClamXAV’s website, a procedure that can be performed manually from the toolbar, via the ClamXAV Sentry, or automatically by specifying the update interval in the app’s preferences dialog. It is advisable you take the time to configure the Freshclam app beforehand, as otherwise you might get a warning stating that the updater and the configuration files of the antivirus do not point to the same virus database.ClamXav for macOS can be setup up as passive or active: scan only the files you tell it to or your entire hard drive, whichever you prefer you can also choose to activate Sentry to monitor your hard drive and scan new files as they arrive. To use them, all you have to do is create a "database" folder inside the installation directory of ClamAV and place them inside. The last two are, obviously, updated more rarely than the first.
There are three different virus databases, namely the daily signatures, the main and the bytecode signatures. The ClamAV Virus Databases contain a package of updated virus definitions that you can use in case your computer goes offline. However, if you find yourself in a situation when you need to update ClamAV's signatures and no Internet connection is available, then the offline virus databases will surely serve you well.
Needless to say, an active Internet connection in mandatory for the updater to be able to contact the ClamAV servers. The ClamAV manual contains instructions on how to set up this application. The only twist is that, this time, the updater runs as a console application named "freshclam", just like the ClamAV engine. The signature database contains information about the latest threats and allows the security tool to identify potentially suspicious files correctly.Īll antivirus solutions deploy integrated updaters to download the latest virus signatures and ClamAV (Clam Antivirus) makes no exception. Using an antivirus to protect your computer against threats is useless if you don't keep the virus definitions up-to-date.
