In past Live Online chats and blog posts, I've mentioned any easy way to temporarily convert a Windows PC into a Linux-based computer in order to ensure that your online banking credentials positively can't be swiped by password-stealing malicious software. What follows is a brief tutorial on how to do that with Ubuntu, one of the more popular bootable Linux installations.
Also known as "Live CDs," these are generally free, Linux-based operating systems that one can download and burn to a CD-Rom or DVD. The beauty of Live CDs is that they can be used to turn a Windows based PC into a provisional Linux computer, as Live CDs allow the user to boot into a Linux operating system without installing anything to the hard drive. Programs on a LiveCD are loaded into system memory, and any changes - such as browsing history or other activity -- are completely wiped away after the machine is shut down. To return to Windows, simply remove the CD from the drive and reboot.
More importantly, malware that is built to steal data from Windows-based systems simply won't load or work when the user is booting from LiveCD.
