Anyway my point is that there is NO WAY of avoiding this software unless your computer usage is very minimal (which I'm assuming yours is, as you are defending that point). You will get spyware very easily, P2P networks will often get you viruses or spyware (I know because I USE them) and even firefox won't protect you from all spyware. Any PC running spybot will most likely get several hundred hits of spyware and adware on their PC.
Did you read my post?
Good job.In my 12+ years of heavy computer usage...
And yes, doing questionable things on your computer is bound to result in spyware and viruses. So don't do it. It's that easy. Or you can just be smart about what you acquire and still won't have a problem (I never have).
