I use a Samsung 7" tablet the only device I have & if I go to look-up certain things, at times it will not let me cause it says it's not a safe area to go to ! I dunno why I does it, but maybe there's a virus or whatever in whatever I'm trying to look-up ! I'm no computer-wiz by far !!What browser? I use Firefox, no problems. And my anti-virus program (Avast) doesn't flag it...
Their site says they are in Virginia, so US... but they do call themselves a wholesale site, so it might not work for you, even if you could get in.
