Talking about 'who-would-like-the-access-to-my-machine' with the point that the previous speaker is a paranoid is plain dumb nowadays.
Yeah, most likely I'm the one who is paraniod right now... I'm running my configurations for the last 17 years (counting my old computers, and days when internet wasn't even existing as an idea, BBSes as stuff), and I never had any problems... people like to click on every single stupid button on those pages, no matter are they full of stupid advertisements like those that promises you a million dollars... of course you already won that money if you believe them

People are really a way out of line sometimes... who cares ? No one, if they are so stupid to click on every single pop-up that comes with some stupid questions, that's their problem. Of course, they are not safe anymore... everyone should be more careful what he/she does on the internet and what pages he/she visits. I, myself, never visited any of those casino or porn pages... that's why I don't have problems with pop-ups (naturally, there will always be some of those in here, but if you're careful enough, no one can assure me to believe in something else... I have a proof and it's right here) or with some nasty browser hijackers...
What I'm telling is, start to worry about your security with yourself first... human factor is huge, then search for reasons elsewhere...
Plus, I never said that using some of those routers/firewalls there will be no risk. That's nonsence and I didn't say anything like that. What I said, is, with all those hardware routers/firewalls, you can drasticaly improve your security, and that's true. Now you're gonna tell me, that routers/firewalls are myth, and we actually don't need them... well, as I stated up there, everyone has rights to has his opinion.
