Although I think AVG Rescue CD can be useful for some cases, there are many other "rescue" disks similar to that.
For "security" checks, not only the user can download those ISO images and use them directly (as oppose to including them in UBCD); but there are also specialized projects that target using several of those rescue disks together.
You can see a list of possible candidates to compete/complement with AVG Rescue CD at the following softpedia link: http://www.softpedia.com/hubs/Rescue-Disks
The list at that link is NOT
fully updated with the latest available versions, but it is useful to show several possibilities. Use it as reference, and download the latest version from the publisher's website, including the latest antivirus definitions.
My own list of security disks includes:
active@ boot disk (shareware)
avg rescue cd
avira antivir rescue disk
bitdefender rescue cd
dr web livecd
escan rescue disk
f-secure rescue disk cd
g data boot cd
kaspersky rescue disk
panda safe cd
norton bootable recovery tool
I can assure you, there are more free security rescue disks.
(Please don't ask me about each of those tools, any web search is your friend
Furthermore, the Shardana Antivirus Rescue Disk Utility (SARDU CD) is aimed at unifying several security rescue disks in one project/tool, the same way as UBCD is excellent at gathering several different tools in one project.
Since there are specialized tools for security issues, IMHO the AVG Rescue CD and equivalent security rescue disks that come as ISO images, could be better left as simple customizations, while adding simple tutorials for adding them to UBCD.
To be completely clear, I am not talking about the other antivirus tools included in UBCD and PartedMagic, but only about complete Security Rescue Disks that are available as separate complete (and big
in size) ISO images.
For the specific case of AVG Rescue Disk (I am just writing what Victor does):
First, download the most updated version.
Second, "gzip" the iso -> avg.iso.gz
Third, put the avg.iso.gz under
to result in: <ubcd-extracted-folder>
Then, for syslinux/isolinux menus, in: <ubcd-extracted-folder>
MENU LABEL AVG Rescue CD V9.0.100
Powerful toolkit for the rescue/repair of infected machines. Suitable for
recovering both Windows/Linux systems (FAT32/NTFS). Includes advanced tools
such as two-pane file manager, Windows registry editor etc.
APPEND iso raw
and for Grub4DOS menus, in: <ubcd-extracted-folder>

map --mem /ubcd/images/avg.iso.gz (hd32)
With respect to AVG Rescue CD downloads, I'm still not sure about which exact "version" would be the best for including in UBCD as customization, since they are cataloged for different media, and they have VERY different sizes (from 18MiB to about 8 times that size).
