Naiupdt, a Perl script to automaticly update your NAI VirusScan DAT/Engine files

* What it is
This script will check the version of the locally installed NAI DAT/Engine file.
Then find the version on the NAI FTP site. If there is a newer version
available, it will retrieve it and install it.
A lot of checks are done to make very sure you will always have a working
DAT file. Including a test with the Eicar test virus.
If the final scan test fails, the working files from before the backup
are restored.

The script has adjustbale logging (using the $verbose variable) for use in CRON.
The default verbosity is set to 5 to check your installation. Please
change to a more suitable value after testing.

* Installation
- Unpack the archive somewhere ( /usr/src for example) and copy the
  naiupdt.pl file to the NAI VS directory (default is /usr/local/uvscan)
- Make sure you put the correct path to Perl in the first line of the script
- Check that the location of the other required binaries is OK
- Do a "chmod u+x naiupdt.pl" in the directory where the file is located
- Do a test run, you can set $verbose = 2 to get informed if an update is
  performed after your testing is finished
