With WINDOWS - nothing is enough!
To be secure when you use ur accounts - use the ultimate Operating System -
http://knoppix.com/ download the image *.iso file. from some server at the download.
Burn it with Nero - or use burn image option. - (In Windows)
Behold - you got a live CD you can boot your computer.
Just hit enter when the boot and image of Knoppix is at the boot display.
If you got broadband Internett - Knoppix is on the internet at once.
There you can surf - both with Mozilla or Konqueror
If you have made some configurations you would like to use next time you open Knoppix - hit the Knoppix Pingvin Icon at the statusline -down left - Enter: configure - Enter: save Knoppix configuration
When the save option pop up - just read the alternatives carefully - (I have not marked the "save all files on the desktop".)
Enter - and you get a pop up windows on where u want the file to be saved - (I have it on a partition.)
The 2 files "knoppix.sh" and "configs.tbz" you better make a backup of.
Remember also that your harddisk is write protected. That is not an obstacle - it is a security.
Next time you boot with Knoppix - you write at the boot startup: "knoppix myconfig=scan"
Then it find your saved configuration image and you are back in business.
I use several programs in Knoppix - wordprosessor - very good divx movie player, (better than windows) - media player - newsprogram - email program - some graphic - and so on.
Download the DVD or CD version
The newest one is v.4.0 or something - but the best is 3.8 with less faults.
