I took an older PC and installed Windows Home Server on it.
Ok now that you have that all in order you still need a virtual system pc which you can use in case you need to click a bad link!
So what you got firewall and an anti-virus with anti-spy - too boot the ID protection stuff and all that.
Go virtual and use a browser with a proxy server setup in case they try to tie you up at your ISP/IP/DNS with a hijacking system for capturing your IP from your ISP and rerouting you to a new DNS server.
It is easy to do and does not cost you anything for software. It is all available free to the public to be used by you for your complete protection.
I have one here on a spare laptop and it does great for IP criss/cross and checking other system at domains/inside and outside.
I like that home server - it does a complete backup almost every night. Plus a system restore via networking is very quick with a n router system. Plus you can pick what you want in folders for sharing to media center for TV and Audio. Then there is that having a good ISP for doing the connect thing of using those PC's from anywhere. I love it and I find it helps a lot while I'm at work and I find I need something or for that matter while traveling and got to go get that file or document I was working on and left it on the computer at home and so forth.
The virtual system I use has no firewall, anti-virus or for that matter anything but a virtual partition for the 2nd OS copy of the original it use's in place of the actual system. Works great - I catch a bug and go as far as I can - even get a copy of the bug to a secure partition on a flash drive and then send the secure file partition to AV/security people to examine for what all they may want to know about it as such. I love that machine it pays in more ways than one! Like the home server too. A good system contains everything you really need to protect you and others that may be with you on the network you use and/or the internet you are all conneted to. Safe is a better way than oh no I should not of done that click... wow!
Nice to see you are going places ID.
