Given that there's not only software bugs, but the hardware ones, I wonder how secure it would be. I personally hate their software, but still, it would be nice to know.

P.S. Security without open-sourcing is impossible. Although, dunno how for other countries, but here in Russia some people have a different point of view.

Some people believe that “opensource is insecure by design, because everyone can see the code”. Probably Kaspersky has the same point.
