+Beware that the **clamd** daemon runs per default with the **clamav user**, if you want regular users to scan their files (e.g. their mail attachments) you have to use the **%%--fdpass%%** argument when invoking the **clamdscan** client, otherwise you will get the error message:
+<code>
+eicar-antivirus.com: lstat() failed: Permission denied. ERROR
+</code>
+The ''%%--fdpass%%'' option works only if ''clamdscan'' connects to ''clamd'' via the Unix socket.
