Having no firewall or AV software is not as big a problem as people may think. I've used a PC's without AV software for a couple of years and been ok (honetly, ya just have to be careful). Having a firewall only complicates things and only seems to be of benefit to people who are running services or who aren't that computer literate.
I would never be so reliant on my PC that any attack can be fixed in 10 minutes (reboot and insert Ghost image) or someone may see sensitive info (ok, theres a picture of my pet fish on the machine somewhere and maybe my Mums phone number). Really depends what you want your PC for though.
Ah well, looks like once again I've found another weird one that won't go away easily
