How To Update Anti-Virus Boot CDs

Hello friends. Over the last 2 days I have downloaded and burned 3 AV Boot CDs. Bitdefender, Kaspersky, and Dr. Web. They all load fine and all. However, I can’t seem to figure out why they won’t update.
My PC is hooked up to the web and works fine in normal mode. When I place any Boot CD in, it loads fine but detects NO internet connection. I am then forced to run a scan with Very OLD definitions.

I don’t see any options where I can get these CDs to somehow link to my connection.
I have an Acer with AMD Processor. What do I do to get these Linux based AV CDs to access my connection while in the bootable environment. What am I not doing!!!
If ANY of you have ever used either of these Boot CDs, please tell me what to do.

                                                           Thanks.

have you concidered a cd/rw (reuse it over and over) possibly or maybe even a memory stick

I don't see any options where I can get these CDs to somehow link to my connection.
I'm not sure what you mean, but I'll try
  1. Restart the computer
  2. the second you restart the computer, keep hitting the “F8” key until a new screen comes up
  3. hopefully 1 of the options will let you run the cd or dvd

Jay2007Tech: Thats not what I meant. ALL Boot CDs I have made burned perfectly and Boot perfectly and work perfectly. They all take me to the bootable environment exactly as they are supposed to.
The only problem is when I access the UPDATE VIRUS DEFINITIONS part of any of the boot cds, they don’t detect an IP Address or any way to access the web. I try to launch the browser and again, no internet connection. What do I do to get a boot cd to find my internet connection! Its always on. Works great in normal and safe mode. Just not in a Linux bootabe environment. Do I have to alter my DNS in Normal Mode to have it detected in the bootable environmrent? How do I solve this problem?

For each of the boot disks, why don't you ask in those forums (like kaspersky forums). http://forum.kaspersky.com/index.php?showforum=4

Hello again. I think I have solved this problem. My Network Card was not turned on. I shall turn it on and try again.

UPDATE: Gentlemen, I have FINALLY discovered the reason why NONE of my boot cds will detect an internet connection and update. It is because I have WIFI! Languy99 I believe, tipped me off to the fact that you must have a LAN connection in order to be able to update boot cds in the bootable environment.
Linux doesn’t yet have the drivers for wifi. Well, at least I know. Hafta either get a wired connection or find someone who has one. I can’t believe Linux doesn’t offer a driver for wifi. Sux.
