Here's another conundrum.....hopefully it hasn't already been answered somewhere else.......when downloading any safe content, there is often times a notice that "you may need to temporarily disable your firewall or virus protection" in order for a download to continue. Why? What is the point in having a virus protection program or firewall, if you're being left open for attack while you're trying to download something else you need? Thanks!

Personally, I've never seen any notice like that.
Can you give us some example?

I've seen it before, for example with Adobe: "You may have to temporarily disable your antivirus software"
http://twitpic.com/2v3otn

It's bad advice, you shouldn't disable your antivirus.

The reason why you sometimes see this, is that the website works with a download manager. That is an ActiveX object that needs to be installed/instantiated in your Internet Explorer. I can imagine that there is antivirus or anti-malware that will react to this and prevent the ActiveX download manager to run properly.
But that's not a reason to disable your AV. They should offer another way to download it. For example, Adobe has also an FTP server where you can download their products.

Flash Player by Adobe (updated version released yesterday) also has the same note about disabling.

Just because they say that doesn't mean you should do it. I would ignore it and in fact I downloaded the new version of Flash yesterday and did ignore it. No problem.
