koaftder is 100% right here. It'd be trivial to modify even known virus/trojan in a way it will get past current virus checkers and scanners.
It's beta sw, if you value stable system, don't install it.
The link should be removed IMO.
@blobrana
you could always block it totally with a firewall just to test
It could still install totally undetectable new virus/trojan to your system.
