QuickStart Guide


  • Download the ClamXav disk image.
  • Drag ClamXav.app from the disk image into your Applications folder
  • Eject the ClamXav disk image
  • Double click ClamXav.app

At this point, you may be prompted to install or update the anti-virus scanning engine. If so, click "Install" and follow the onscreen instructions. Once the installer has finished, you may need to double click ClamXav.app again.

Update From a Previous Version

If you previously downloaded ClamXav from the Mac App Store, please understand that it is no longer available in the App Store, so it's not possible to update automatically to the new ClamXav. Please drag your existing ClamXav.app to the trash, and download from here.

If you downloaded ClamXav through this website, launch it and go to the ClamXav menu, then select "Check for ClamXav Updates…" and follow the prompts.

Main Window

When you launch ClamXav, you'll be presented with the main window. It contains five primary sections:

  • Toolbar
  • Source List
  • Infection List
  • Console
  • Status Area

The toolbar at the top of the window allows quick access to frequently performed actions - it can be customised from the View menu.

The source list on the left hand side allows you to keep a list of favourite items to scan.

The infection list on the upper right hand side shows details of any infected files found during a scan.

The console area on the lower right of the window gives verbose output about what ClamXav is doing.

The status area is the bar at the very bottom of the window. Initially, it displays the version of ClamXav and your current scanning engine version. It changes during a scan to show which file is currently being examined. To the right of this is a progress bar to give an indication of how many files in your selection are still waiting to be scanned.

First Scan

Make sure you're connected to the internet and click "Update Definitions" from the toolbar. ClamXav will attempt to connect to the Internet to download and install new virus definitions.

Wait until you see "Update Finished" appear in the console area at the bottom of the window.

Select an item to scan from the source list on the left or click the plus (+) button at the bottom to add a different file or folder to the list. Alternatively, drag a file or folder into the window from the Finder to scan it immediately.

Click the "Start Scan" button. A scan can be aborted safely at any point.

If an infected file is found, the name of the file and the name of the infection it contains will be displayed in the "Infection List" in the top half of the window.

Dealing with Infected Files
Virus Found

If a file shows up in the Infection List, don't worry. There are a number of options available to you; Select the infected file from the list and then go to the File menu » Infection List and choose one of the options:

  • Show Path
  • Reveal in Finder
  • Exclude from Future Scans
  • Quarantine
  • Delete

Be very careful with the Quarantine and Delete options as both of these will move the file on your hard disk. If the file in question is an email or part of a mailbox, you probably don't want to delete or quarantine it.
