I just tried to install the new beta, and Windows and AVG both prevented me to install it, AVG even telling me they found a "rare virus" . OK

Now I'm pretty sure it's just a false positive, but just in case I'm asking if it's safe and what in th e64 -bit installer might trigger my anti-virus defenses?

edit: I cried wolf too soon. My AVG was out of date and after updating, everything's fine.
