What is ClamXav?

ClamXav is a free virus checker for Mac OS X. It uses the tried, tested and very popular ClamAV open source antivirus engine as a back end.

Back in the days before OS X, the number of viruses which attacked Macintosh users totalled somewhere between about 60 and 80. Today, the number of viruses actively attacking OS X users is relatively small. However, this doesn't mean you should get complacent about checking incoming email attachments or web downloads, for two reasons. Firstly, there's no guarantee that Mac users will continue to enjoy the status quo, but more importantly, the majority of the computing world use machines running MS Windows, for which an enormous quantity of viruses exist, so it's necessary to be vigilant in checking the files that are passed on to friends and colleagues.

How do I install it?

The instructions that follow will guide you through the installation process.

System Requirements

• MacOS X 10.3 or later
• At least 32MB of memory
• At least 25MB of free disk space
• Administrative rights on the system

STEP 1: Mount the disk image

Download ClamXav and save the .dmg file to your desktop. Once the download completes, double-click the file to mount the disk image. It should then appear in a finder window.

STEP 2: Install the Application

Drag the ClamXav application from the finder window to the Applications or Applications/Utilities folder.

STEP 3: Create a Shortcut

Drag the ClamXav application from the Applications window to the Dock.

STEP 4: Update ClamXav - Internet connection required

Start ClamXav by clicking on the shortcut in the Dock . Once the application starts, update the virus definitions by clicking the Update virus definitions button.

STEP 5: Scan Your System

In order to make sure your system is clean, you should perform a manual scan. Click the Choose what to scan... button and then select the folder or files to scan. Once you have made your selections, click the Start Scan button.

STEP 6: Configure Updates and Scans

To keep your system clean, you must schedule updates for the software and regularly scan your system. Click the Preferences button.

Now select the General tab and make the following changes to the configuration:

1. Check the following boxes:
   • Log the scan results to file
   • Log the update results to file
   • Monitor scan with progress bar
   • Alert on virus detection
   • Scan e-mail files
   
   
2. Uncheck the following boxes:
   • Quarantine infected files to
   • Do NOT scan if the file name contains
   • Only scan if filename contains

Select the Internet tab and make the following changes:

1. Check the Check for new version of ClamXav, Check for new version of ClamXav engine, and Update virus definitions boxes.

Select the Schedule tab and then make sure Scan is selected. Choose a time to run a full system scan and then click Save Schedule Settings. If your system is not on during this time, a full scan will not be performed. Full scans can be quite intensive and may be disruptive while working on the system, so it is recommended that you choose a time when your system will be on but unused.

Click the Update tab on the page. Choose a time to update the DAT / pattern files for ClamXav. Be sure to click Save Schedule Settings once you have configured your update time. If you have previously scheduled updates, but it appears to have returned to the default settings, try clicking the Re-load Schedule Settings button.

You should schedule your updates before running your system scan so that the DAT files are up-to-date before a scan is performed.

STEP 7: Configure Automatic Scanning

ClamXav can "watch" folders for you so that items can be scanned as they are saved to your computer. The current version of the software cannot automatically scan DMG files or Firefox downloads. You can manually scan these files after they have been downloaded. To enable Folder Sentry for automatic scanning:

1. From the Preferences dialog, select the Folder Sentry tab.
2. Drag a folder from any Finder window or the Desktop into the list.
3. Repeat this for any folder you wish to watch. Please note that Folder Sentry will NOT scan subfolders automatically. If you wish to scan a subfolder of a folder in the list, you must add that folder separately.
4. Check the Scan inserted disks... and Launch ClamXav Sentry when you log in... boxes.
5. Click the Save Settings & Launch ClamXav Sentry button.
6. If you add folders at a later time, you will need to restart the sentry program.

Congratulations! ClamXAv is installed.
