VPN's are a good idea but all the methods (including the linux option) are vulnerable to the hardware based keyloggers and the packet sniffers. The method linked above does work to make those methods a bit harder for the hackers to use. There is no foolproof solution but this method would thwart the hackers that aren't all that smart. Hopefully, the one's smart enough to thwart this method are working on breaking into the Federal Reserve or working for the CIA.
