I think a little bit of paranoia is a good thing.
Especially when we have people creating such crap as viruses, trojans, worms. Neither of these take into consideration who the hell you are. There's no explanation why these idiots create, these types of things, other than they can, and don't give a 5h*t.
Then there's Spyware, the only difference is that we know why they are created, because Advertisers can sell their junky product. Some spyware, known as malware, can mimic keyloggers, and record your keystrokes, passwords, and credit card numbers. Some hijack are browsers, and instant ka-ching for the spyware author and affiliate sites.
Paranoia, is a good thing, because you can at least prevent becoming a victim.
@sportswidow05: You might invest in a print server, however, your printer needs an ethernet port for this work. If you don't have one, I've heard there might some sort of usb device you can hook up to your printer if it supports usb. Once you connect your printer to the print server, you need to assign your printer an ipaddress, then do the same in windows under the printer's property. This will allow you to share your printer, between two computers, and you don't even need the host computer, where the printer is connected to, to be on.
Here's an example of one, I'm not recommending this one, this is only to show what one look like:
