  <title>Scanning for Potentially Unwanted Programs</title>

<p>You may wish to set specific preferences for <app>ClamTk</app> usage.  To do so, click the <gui>Settings</gui> button or click <keyseq><key>ctrl-S</key></keyseq>.</p>

<p>Potentially Unwanted Programs - or PUAs - are typically defined as programs that fall into a grey area - that is, the intent behind their use and whoever is using them plays a role in determing whether you want them on your system or not.</p>

<p>For example, tools such as "sniffers", password crackers, and port scanners can all be considered useful from an administrator's perspective, but may also be used by individuals with malicious intent.</p>

<p>When <app>ClamTk</app> reports an item prefaced with "PUA" in the signature, these are things to keep in mind.</p>

<p>To enable this feature, select the option as indicated below.</p>
