Mike...You probably already know but most Trojans enter your pc via email,so don't open email with attachment from people you don't know.
But I've heard that a normal picture (jpg) can have a trojan or virus init, what I never had thought it would be possible.
Besides a software firewall you can also connect your pc via a router which also have a firewall inside so you are protected
by 2 firewalls.
As for passwords...don't use easy passwords like the name of your cat but use letters and figures.
I think it's impossible to protect your pc for 100% but you can make it difficult and that could be a reason for a hacker to search for an easier prey.
