A router's firewall WILL block you from getting internet based spyware/adware installed but if you install something like yahoo toolbar you are allowing your computer spyware that way.

A router will absolutely not do any of that. What you are describing is called content filtering and it would need to be done by a real time proxy scanner. There are absolutely NO home user products that would do this via a router.
A router can protect your system by not allowing traffic directly in to you. Most often it does this by port filtering. When you request something from the web (on port 80) it will allow information back from that address via a random port that the webserver communicates to the client it will be transmitting over. The router doesn't care what any of that information is - whether its a virus, spyware, adware, or whatever. Routers do not do content filtering.
Google and Yahoo toolbar are not spyware. Spyware is something placed on your system without your permission. Adware is placed on your system with your permission (you are told about it in the click-through EULA). I know that google's toolbar will send data back to google about your browsing habits, but you have the option to turn that off if you wish to. I do not know about Yahoo's toolbar, but I do know that it is absolutly not spyware.
you need to reread what you just said. A router does stop you from getting spyware/adware/virus's that you dont tell or allow your computer to install because it blocks the ports that those virus's spyware/adware try to connect to your computer on. thats exactly what I said and exactly what you just said.
Heh, no we did not say the same thing. There seems to be a fundamental misunderstanding on your part on how viruses, adware and spyware work. I'll break down the most common ways for you.
You have requested that webpage, and because the router does not
check the content (content filtering) it will allow any page you have gone to, to load. This means if you have a router and visit a website like this, you will get a virus unless your anti-virus solution is on the ball. This scenerio covers pretty much all spyware infections.
Virus #2: You receive an infected email. You open this, it infects your system. A router will do nothing to stop this.
You told your email client to go fetch your mail, and your router allowed this traffic through..again not checking the content of what you asked for. And again, unless your anti-virus solution..blahblahblah. You get the gist.
Virus #3: Someone on your local broadband network is infected. This means someone on the same broadband network as you (e.g. comcast, verizon, etc) is infected and is blasting out the viruses over ports 139/445. A router WILL stop this traffic from coming in.
Adware #4: You download a program that claims to provide a service for you (keeping track of your username/passwords on websites like gator, etc) and while it does what you ask, it also installs adware to pay for its services. This is legal because the EULA it asks you to accept for the install tells you about this. A router will do nothing to stop this.
Routers do, as you stated, stop direct attacks against your machine from the outside. However I can tell you with 100% certainty that the vast majority of viruses and do not infect people via that method, and spyware does not utilize that method either.
