Question : TightVNC security

I want to remotely access my computers and want to know of security solutions for doing this.  I cannot figure out how to install OpenSSH on my xp machine.  Are there other protocols that you would recommend or other options in terms of programs?

I do not want to spend much money.  I like the idea of gotomypc.com but it is cost prohibitive.

Thank you,

Here is a link on the software you can download for using SSH in windows:

A rough guide on how to do it:

Let me know if it works as I am quite interested in it myself! ;p
