Installation</A>
</H2>
<P>
Please read the README file in the current version, because it probably
contains some important release notes.
If you are installing Clam AV for the first time, you have to add a new user
and group to your system - <I>clamav</I>: <A NAME="tex2html9"
HREF="footnode.html#foot450"><SUP>2</SUP></A>
<P>
<PRE>
# groupadd clamav
# useradd -g clamav -s /bin/false -c "Clam AntiVirus" clamav
</PRE>
<P>
The above method works on Linux and Solaris, if you don't have
<I>groupadd, useradd</I> please consult your system manual - the section
about creating new users and groups.
If you are not a system administrator or won't be using <B>clamscan</B>
in superuser mode, you may omit this step with the option
<I>-disable-clamav</I> passed to the <I>configure</I> script:
<PRE>
$ ./configure --disable-clamav
</PRE>
This disables testing for <I>clamav</I> user and group. <B>clamscan</B>
still requires <I>clamav</I> for superuser mode. Please don't set a password
on this account, just assure it's locked with "<B>!</B>" in
<I>/etc/passwd</I> or <I>/etc/shadow</I>. It must be a normal, unprivileged
user. Don't add it to any special groups.
<BR>
<BR>
<P>
After this, extract the archive, configure and compile:
<PRE>
$ tar zxpvf clamav-x.yz.tar.gz
$ cd clamav-x.yz
$ ./configure; make
$ su -c "make install"
</PRE>
<P>
<B>WARNING: Never set SUID/SGID bit on Clam AntiVirus programs.</B>
