I really would like to tighten my computer and internet security, so can someone provide me with helpful suggestions. Would you recommend the browser SeaMonkey, or Firefox? Keep in mind, I want the most secure browser. Good free secure email accounts you can make apart from Hushmail? How to permanently delete files from the computer so hackers can't recover them? Plus, for example, let's say you've entered a race and your results come online, how do you get them deleted? Because I want to completely protect my identity online. And lastly, how do you stop spam coming into your Bigpond account? I probably get around 50 spam emails per day - do you think I should change my email address and become more strict on who I contact?
