For on-line banking or other financial related transactions I boot my computer with the Linux operating system directly from a CD (Knoppix 4). This gives considerable protection because any hardware disk storage is defaulted to read only. This prevents any malware from being stored on your computer. Booting from a CD is certainly not convenient but I'm willing to go through the trouble to gain the extra security. It's still not 100% certain security but it's close.
