Thank for all your replies.
On a rainy, quiet Sunday morning i did some digging with Google and i came across three websites that set me straight or at least left me wondering. If i would have read them before posting this thread i would probably never have posted it.
The three are: www.matousec.com: Security software testing, analyses, research and reviews.
---->projects ------>proactive security challenge http://techsupportalert.com/
----->enter 'matousec' in the search box. The Older Geek*|*
-------> enter 'how to test your firewall' in the search box.
Pages and pages of text.
The second link above has some heavy criticism of what the matousec site says and how it tests. Quote:
"Some of the site's claims are misleading".
In one of the three sites it says that leak tests, including the one from Gibson Research, are outdated, i.e. useless.
All of them have, btw, lists of best AVs and firewalls.
So now i am wondering about everything: tests, best "whatever", etc.
The worst part is that even testing the security of a system seems rigged, biased or may be influenced by commercial interests or testing is carried out for properties that are not claimed by the programs tested (and then handed out bad marks). You simply don't know any longer what you can trust and what not.
