This malware site resides on the one and the same IP: https://www.virustotal.com/nl/url/a250cdcf4f21453cc8d1c25f8327dddc86e24a6966f16918a07fde47af1af18e/analysis/1384699476/

and htxp://jipin.bj0574.com is in Dr.Web malicious sites list!

I hope users now understand why I run DrWeb url checker in the browser next to avast residential
as a kind of “additional rear mirror extension”.
I always got a lot of flank cover from that DrWeb extension because of overlapping detection range.
Our user Dim@rik knows why ;).
By the way BitDefender Traffic Light is blocking this site as well.
