     Because the engine structure occupies a few megabytes of system memory, you

+    \subsubsection{Forking daemons}
+    If you're using libclamav with a forking daemon you should call
+    \verb+srand()+ inside a forked child before making any calls to the
+    libclamav functions. This will avoid possible collisions with temporary
+    filenames created by other processes of the daemon. This procedure
+    is not required for multi-threaded daemons.

     \subsubsection{clamav-config}
     Use \verb+clamav-config+ to check compilation information for libclamav.
