When you need a hex decoder and Google translate...

Seen this suspicious SE redirect code: http://killmalware.com/biyoranking.com/

/最安値「エクオール」サプリを買う前に必ず読む

which is Japanese for
Lowest price “Equ*l” Be sure to read before purchasing a supplement

So we can establish we are dealing with pharma spam.
