There will be a time when you end up using a remote or temporary host PC to access the Internet. We always recommend you use portable applications on your host PC so that you do not leave any trace behind when you browse the Internet. The web history and cookie information will be written back to the portable apps, rather than to the host PC. Problem is that you have to use an ISP to access the Internet and this ISP can trace your traffic, browsing habits and the amount of data you download to the PC.15 Jan 2009
