Not long ago, I took a look at security software from Keynesis called Lockngo. Keynesis also has a program to compliment Lockngo called Portable Sweeper. The two programs together provide a great set of tools for anyone wishing to have their portable devices secure and safe. Portable Sweeper is a bit different in that it cleans your system or your hosts system of all traces that you were on it and what you were doing on it. Let's take a closer look and you can get a better idea of what I am talking about. - thinkcomputers.org
