Trojan horse bypassing any firewall and antivirus SW

["Alexey Eremenko" <al4321 () gmail com>]

This is *not* possible to bypass unknown protection, similarly it is
*not* possible to attack an "abstract PC" without knowing which OS &
software is running on it.

If you have firewall, it will probably stop them.

If your OS is non-Windows, you will make their jobs harder - next to
impossible with proper Linux or OpenBSD configuration.

What they tell you - that they can break any protection of any OS is a bull.

> Zero-day exploited code might just do the trick, AFAIK.

Zero day exploit cannots target all operating systems in the world.
