Quick Start Guide

Installation & registration

First of all, download the latest version of ClamXAV and double click in your Downloads Folder – this expands the file to (your web browser may do this automatically). Drag to your Applications Folder and double click on it to complete the installation process.

Then simply click the link in the registration email to enter your registration key automatically or click the Enter Registration button and copy and paste the details from your email. (Incidentally, if you ever misplace your registration details (your ‘key’) you’re not alone – our Lost Key Retrieval service is rather popular… )

Next, you’ll be asked to enter your admin name and password (the ones you use to log on to your computer, this isn’t something that’s specific to ClamXAV) to install the Helper Tool. Then just follow the prompts to install the scanning engine and update your virus definitions.


Welcome aboard! Time for a quick tour. When you launch ClamXAV, you’ll see a main window with five primary sections. Here’s what they are and what they do:

Toolbar: allows quick access to frequently performed actions

Source List: allows you to keep a list of favourite items to scan

Infection List: shows details of any infected files found during a scan

Console: tells you exactly what ClamXAV is doing at any given time

Status Area: displays the version of ClamXAV you’ve installed and the date of your latest virus definitions update; during a scan, this changes to show you which file is being examined and there’s also a progress bar showing how many files are still to be scanned

Your first scan

Having made sure you’re connected to the internet, click Update Definitions on the toolbar; ClamXAV will install any new virus definitions and show these being downloaded on the progress panel (which disappears when it’s finished). A quick scan of your system happens every time your virus definitions are updated and when any selected items on your Source List are scanned.

Now, you can either select an item to scan from the Source List; or click the plus (+) button at the bottom of the list to add a different file or folder; or – if you want to scan a file or folder immediately – just drag it from the Finder/Desktop on your Mac into the window.

Click Start Scan and you’re off. Remember than you can stop scanning at any point and, if the Start Scan button is greyed out and can’t be clicked, it probably means you haven’t selected an item to be scanned from your Source List (don’t worry, we’ve all done that at least once).

Dealing with infected files

The name of any system infection or infected file will be colour-coded on the Infection List:

Blue         low concern but consider quarantining the file to avoid passing the risk

Orange   medium concern and needs to be quarantined

Red          high concern and should be deleted

Green     neutralized threat

All you need to do now is choose one of the following actions:

Quarantine or Delete: if you don’t need the file

Exclude from Future Scans: if you do need the file

Show Path or Reveal in Finder: if you’re not sure and want to check first


Be careful with Quarantine and Delete as these will move the file on your hard drive. If you delete or quarantine a file by accident, immediately right click on it (or hold control key and click if you’ve got a one-button mouse) and select Put Back – don’t worry, you can’t put back a system infection.

ClamXAV is now comfortably settled in my applications folder and Genieo [adware] is eradicated from my hard disk as well. Thank you for all your help in cleaning up my computer.
