  <title>Updating antivirus signatures</title>

<p>Like most modern security programs, updated signatures are essential.</p>

<p>If you have chosen to update signatures manually, select the "Update"
option.  You will see a dialog similar to the image below:</p>

<media type="image" mime="image/png" src="figures/clamtk-update1.png" />

<p>You are viewing the versions of the locally installed programs - of the
signatures, and the GUI (ClamTk itself).  Press OK to check for updates.</p>

<p>If updates are available, a dialog similar to the image below will be
shown:</p>

<media type="image" mime="image/png" src="figures/clamtk-update2.png" />

<p>To update your antivirus signatures, press "Update".  You should see a
progressbar animate as signatures are downloaded:</p>

<media type="image" mime="image/png" src="figures/clamtk-update3.png" />

<p>This could take some time depending on how many updates need to be
downloaded.  Once complete, the screen will refresh.</p>

<p>A similar view will appear if no new updates are available from the start.</p>
