I have an idea.
You are going to need about a 20GB or less of an external drive, right? How about you go ahead with this, make a back up or clone image of the external drive, then use the external drive as you wish. When you finish just do a quick format of it and copy everything back to it. No virus, and it will only take you a few min each time.
