The real work nowadays is outbound protection, stopping what has entered your system from phoning home with your user names, passwords, etc.
David I agree with you but I've got to allow it through my Outpost undeveloped firewall so it's my decision not the firewalls. Do you agree that I have the ultimate decision on what goes through my firewall. OK things might get in under a false name or in disguise but surely a competent PC user will immediately notice changes in their PCs behavior and rectify it.
No I don't agree that ultimately you have the choice of what goes through your firewall. That is the whole point programs can exploit the firewall and you will never now it is making an outbound connection, re read what I said.
Spyware and malware may well not want you to know and go to lengths to either hide or keep a low profile so you don't see an appreciable change in your PCs behaviour, not to mention the competency of the user most are ignorant of the subtleties of malware.
As for the idea that corporate business users should pay for the freeloading home users it doesn't deserve my expletive comment even though I'm a freeloading home user. There's more to it than that or can you explain after years of advert support the free Opera browser it has now become an ad free browser anyone can download for zilch.
Effectively they had to, it had less than 1% share of the browser market and it wasn't going anywhere, that would obviously change when it became free without ads (I didn't swallow the altruistic drivel drivel they had on the web site when it went free). I have no idea how they could give up the ad stream revenue, obviously they found a way, why they didn't do this sooner is the question.
Unfortunately, I doubt that the free firewalls are likely to keep up as this development costs money.
David look back at my comment about the free Opera browser then explain your doubts.
I have and I can't understand how they could do it without the ad revenue supporting the free product otherwise they would have done it in the first place.
Most of the free firewalls don't have the full functionality or protection of the paid for version and that is why many but the pro version. Development costs money and if you only have a free product someone has to pay or you need a generous benefactor.
