Transferring Infected Files?

  Date: Dec 11    Category: Unix / Linux / Ubuntu    Views: 481
  

In spite of the firewall and anti-virus programs
installed, he managed to infect my wife's (XP SP3) desktop with a plethora of
viruses. AVG cannot clear all of the viruses and my wife is not ready to cut
over to Linux, so I will have to wipe her drives and re-install XP.

The plan is to move her personal files over to an external drive on the USB port
before wiping the hard drives. The options are: move the files while working
from her desktop, move the files over the network using a Vista machine, or move
the files over the network from a Linux machine.

Working from the Linux machine, I don't have to worry about it getting infected,
and if I partition the USB drive as ext3, I don't have to worry about the drive
getting infected, either. If I move the files using a Vista machine, it's
firewall and anti-virus software may detect and block infected files during the
transfer process.

I moved the files from an infected computer over the LAN to my Linux
computer, scanned them with Avast
antivirus, government wiped the hard drive, re-installed WindowsXP,
transferred the files back, and ended up re-infecting the computer. I
finally found the one file that was the source of the infection and
deleted it from the Linux copy.

But I'm not here to snipe, I have a couple of suggestions. Rather than subject
your newly reinstalled XP box to possible attack during the update process,
check out ctupdate.

You can use a known clean Windows computer to download the latest MS updates,
burn them to CD, and patch your XP install before ever putting it online. I use
it whenever I do a fresh Windows install.

Once your computer is fully patched and all of your major software installed,
use the Linux app "partimage" to create an image of the new, clean install.
Then, if it gets infected again, just backup files, wipe the drive and transfer
the image. The easiest way to do this is to remove the hard drive from the
Windows box, install it as a second hard drive in a Linux computer and do the
backup/restore imaging/reimaging in Linux.

Instead of using virus files, try some test virus files from the European Expert
Group for IT-Security:

Virus sample files.

I installed Avast for Linux (the .deb
package), registered it and downloaded those eicar.com files. It found and
deleted them, but nothing else so far. It will be interesting to see what it
finds on some DVDs.
Please send me some sites that are infected with viruses and try to do
unattended downloads.
