I have a client who asked me to build them a USB drive that, when inserted in to a windows machine that is already booted up, it will automatically update the definitions then do a scan. I'm new to ClamWin and I don't know all the parameters to put it together. I know it is an odd request, but has anyone else done this?

You should be able to do it with an autorun file on the USB that runs a ClamWin update script. However, Microsoft disabled autorun as default like it used to be, so you may have to enable it on each Windows computer that uses the USB. I would keep the USB plugged into a computer somewhere and have ClamWin update every hour, if this is okay in the environment in which it will be used. I'm not a script kiddie, but I'm sure there are some ClamWin update scripts around.

I hope your client is using another AV besides ClamWin. It is not a real-time AV, and the signatures are not as many as are needed for good protection--especially in a business/commercial environment.

The advantage of linux and unix is that you should be able to design your own security drive. You need to use the linux or unix versions such as clamv. The advantage is that it should be able to offer good customer security. you need to use usb mounting software and set the bios to run the USB device.Most mainstream distribution will have this facility.
