OK If you're a brave sole try this.
Edit the autoupdate script
---------------------
# if we've got this far then the update works so link it to
# where the virus scanner will look for it
chdir $mcafeeroot or &BailOut("Cannot cd $mcafeeroot, $!");
my($OldLinkTarget) = readlink $DATlink;
&LockMcafee();
system("$rm -f $DATlink");
system("ln -s $DATdir $DATlink");
#unlink $DATlink;
#symlink $DATdir, $DATlink;
---------------------
Find the lines above that do the unlink and symlink and put #'s in front of
them. Insert system calls like I show above. Save the autoupdate script. rm
-Rf the existing 20020208 dat directory and run ./autoupdate from the
command line again.
If the rm -f $DATlink has a problem the system call will show an error to
stderr (console).
If the ln -s $DATdir $DATlink has a problem you will see that error as well.
Let us know the output exactly!

Hmm, If I rm -Rf /usr/local/mcafee/20020208
then run autoupdate
I get the following output.
> /usr/local/mcafee/autoupdate
A target has not been specified for scanning! /usr/local/mcafee/dat
/usr/local/mcafee/20020208 /usr/local/mcafee/20020208
Notice the three lines printed after the uvscan error message. The first one
is the DATlink (should always be /usr/local/mcafee/dat) The second is the
OldLinkTarget (what previous version of the dat you were
using)
The third is the new DATdir. (the newly downloaded and untarred version)
The DATlink should point at DATdir. The OldLinkTarget should be deleted if
its really an old one.
In your post it shows only one line (I can't match it up to tell if that's
OldLinkTarget or Datdir. In my example the OldLinkTarget is the same because
I had no previous version. I just deleted the 20020208 directory and ran the
script again. However ALL three lines should print. You might have to make
the symlink the first time but that should not be necessary.
Try it anyway
cd /usr/local/mcafee
ln -s 20020208 dat
That way your uvscan will work when mailscanner tries to use it.
To test my theory,
Do a rm -Rf /usr/local/mcafee/20020208
Then run autoupdate again. If you get the same printout as I got above then
it should work later when the newer dat files come out. If that's the case
then your system won't make the initial symlink the first time around. Yuk.
Let us know!.
Good Luck.

ls -l /usr/local/mcafee/dat
It should show something like this below!
lrwxrwxrwx 1 root root 26 Feb 8 04:02
/usr/local/mcafee/dat -> /usr/local/mcafee/20020208

I'm not really strong with Unix so could you tell me how I could
check that.

Check to see if /usr/local/mcafee/dat is now a symlink
To your /usr/local/mcafee/20020208
The script should relink it each time it untars a new dat file
archive.
The error message "A target has not been specified for scanning" is
a normal
error message printed out by uvscan when the autoupdate script tests
the dat
files to see if they work. Since the test is actually scanning
nothing, it
returns the message!
Hope this helps.

Those changes are there. When I run autoupdate here is what is
returned.
[root at yoda mcafee]# ./autoupdate
A target has not been specified for scanning! /usr/local/mcafee/dat
/usr/local/mcafee/20020208
The tar is copied and extracted to 20020208 but they're not being
moved over
to the DAT directory.

One would expect, but who knows? Here is what you have to change to
get this
to work (from a message on this list on 15 Jan from Lawrence E.
Bartash --
gotta give credit where credit is due):
------------------------------------------------------------------------

OK I got this one fixed.
Taking braces out does absolutely nothing.
I changed the perl calls to system calls temporarily and noticed
that
$DATlink had a trailing / on it. Very bad, perl doesn't barf on
this! :-(
therefore the real fix is on line 39
<my($DATlink) = "$mcafeeroot/dat/";
>my($DATlink) = "$mcafeeroot/dat";
also line 123 needs to be changed
<print "DATDir\n";
>print "DATdir\n";
