1 Safe Browsing

For a safe browsing environment for things like on-line banking, here's my current recommendation.

1.1 Initial downloads

• Download VMware player (www.vmware.com)
• Download the latest version of Ubuntu (32 bit) as an ISO file

1.2 Install Ubuntu

• Install VMware player
• Start VMware player and create a new virtual machine
• Specify the Ubuntu ISO you downloaded earlier as the installation
• Answer the other VMware questions
• Allow VMware to install it's add on for Ubuntu
  • On Windows 7 you need to approve admin rights for the VMware add on, so wait for it to pop up. If it times out, the add on won't install
• Wait for the install to finish

1.3 Finalize Browser

• Log onto Ubuntu
• Start Firefox
• Install NoScript for Firefox (noscript.net)
  • Read the instructions on NoScript. It is intrusive and annoying, but it's far safer with NoScript.
• Install Web of Trust for Firefox (www.mywot.com)
• Install Perspectives for Firefox (perspectives-project.org)

1.4 Other Notes

• All software is free
• You need a reasonably powerful machine
• The Firefox plugins are recommended for all browsing environments.
• Using a netbook as an Ubuntu machine for secure browsing is an option, but I had issues with getting Ubuntu drivers for my netbook.

  • Try HijackThis, which won't detect infestations, but will tell you all the possible problems. http://sourceforge.net/projects/hjt/
  • ComboFix, which will clean some problems, but is intended to produce a report that can be posted on a forum to get help. http://www.bleepingcomputer.com/combofix/how-to-use-combofix
