This method works to protect your computer from malware, spyware, virii and government spies checking up on you. This method works best on a freshly
formatted HD with a new OS, only because you may already have malicious software installed that you are unaware of.
First download VirtualBox here: www.virtualbox.org...
If you don't already know VirtualBox is a virtual PC that runs on your current operating system. If you are running on Windows you can install
VirtualBox and run any other operating system in a window as if it were any other application running in Windows. The OS running in VirtualBox is
called a guest OS and your main OS is called your host OS. Basically the guest OS thinks it is running on it's own PC when it is in fact just running
off of a file on your hard drive. Any files you save on your guest OS will be stored in a file on your hard drive.
Download an operating system, I recommend a Linux distribution such as Ubuntu: www.ubuntu.com
Here's the deal. You'll need a firewall installed, if you're on Windows the Windows Firewall will work fine. Setup all of your firewall profiles to
block all inbound and outbound connections that do not match a rule specifically setup to allow the connection. If you're using Windows Firewall a
few rules are already setup to allow certain connections, go into the advanced settings and disable all rules except for those related to core
networking. This will block all applications from accessing the internet, including internet explorer or any web browsers you have installed. Now
setup an inbound and outbound rule to allow only VirtualBox access to the internet.
Startup your VirtualBox system and do all of your web browsing and internet activity through your guest OS. Any spyware, malware, virii downloaded
will think that is has infected your system, but it has actually only infected one file on your hard drive, it will not be able to spread to your host
OS because it does not even know there is a host OS.
Instructions on the VirtualBox website should be able to help you get your guest OS up and running, but if you need additional help you're welcome to
post here and I'll see if I can offer assistance. I've been using this method for almost a year and my system still runs like new.
I forgot to mention that VirtualBox allows you to setup a 'network' folder with your host OS so you can transfer files between the two. I recommend
NOT setting up networking between your host and guest operating systems, this would allow any software or hacker access to your host OS through your
guest OS. If you need to transfer files between the two use a USB disk or something of the like.
