For the 5 blacklists, i don’t know if it is the main reason,
i think many sites are listed in some blacklist.

We have 10 more stores, more than 5 have blacklists ,
such as another store http://www.BestR4i3DS.com (IP: 46.29.249.186 ),
please check it, it aslo has 5 blacklist.
but bestr4i3ds.com without problems in Avast.
