What is this "URL:Mal" that keeps popping up in Chrome apparently?

I’m only on google docs and drive, and Avast has given me four notifications that it’s blocked the exact same thing, a “hxxp://54.69.57.41/e/a-1177/s-2113/c-649/g-2144.xgi?pkey=bijo15bijox40&chpcm=&chpsg=&chpcr=&chpck=&rand=RANDOM&chpth”

I am really concerned, someome please help?
