With Boot Rescue CD, where do updates go.

[mm]

I've learned a bunch about antiviurs rescue CDs in the last few days.

In the last post, I forgot to say that BitDefender was run from a
rescue CD. When it starts, it first dl's any virus definitions that
it has created since the .iso file was written. In BitD's case, that
was about 4 days, and it didn't take very long to fetch the updates.

When I was done running the CD, I looked at its contents and there
were no new files, and of course not everyone with a virus runs the CD
in a CD burner.

Does that mean the updates are lost and will have to be retrieved
again if the CD is run again??


Similarly, I dl'ed the Kaspersky CD and iirc that CD had a date of 3
or 4 months ago, and it took about an hour to dl the updates. Those
are lost too now that I rebooted the computer, right?

I don't really mind, but I woudl still like to know. (I had her pick
up the CD (for BitD) at my house and I talked her though starting it
over the phone, then had her leave the computer on until she finished
sleeping and went out until 3PM and I got there after that. But next
time with someone else it may not work out that well, so i'd like to
know.)

Does anyone know if it is typical for Kaspersky's file to be 3 or 4
months old?

Why would a rescue CDs be set up to automatically burn updated
definitions to a CD-RW? Think about it: if they did that, malware could
use it too, and insert itself into the rescue CD. In any case, never use
a CD-RW for a rescue disk, just in case.

Aha. Okay. Thanks.
