Ist ar.voicefive.com sicher?

I'm not a person who usually ends up with browser hijacks but somehow this voice five 'survey' thing magically appeared in a new tab twice now. none of my usual security keeps it from starting although thankfully it hasn't actually loaded. I'm going to do some digging and see it it's a standard below the radar BHO or something more malicious... and it's going AWAY!

This has opened a few times for me recently, though I've not been to any remotely sketchy site (I've only followed internal links and manually typed in addresses, with a couple exceptions I was able to check with internals), nor have I downloaded anything that I wasn't both expecting and from a trusted sender. However, I know this is a malware site. MalwareBytes couldn't find anything (multiple scans, scanning anything possible). Help?

This stupid website started popping up on me as of recently; I've never been on it voluntarily... it just keeps popping up at random times... especially if I am watching something on my computer, which is really annoying because then it gets interrupted. I don't know how to get it to stop.
