I think both of them are not the main problems:
the first one, please compare our another store: http://mxtoolbox.com/domain/www.mtcard3ds.com/?source=findmonitors ,
the result is almost the same as 4coolday.com
but www.mtcard3ds.com without any problem in avast.

second one: friendsdatebook.com is the host name, i just tracerted another store: www.flashcarts.ru (158.255.2.167),
at last IP resolves to resolves to 158-255-2-167.linkhost.us not flashcarts.ru too,
flashcarts.ru is no problem in avast too,
:‘( :’( :cry: ,please help!
