Microsoft Windows (choose incarnation) is notoriously insecure. Proof: use any program to supposedly erase your tracks. Then reload a previously surfed page. It will load faster from cached pages regardless of cleaning (paranoia tab in tweakui for example). The only way to surf in a secure way, is from a linux bootable floppy with a firewall or proxy server and a non-caching browser on a diskless workstation. Period.
