Aww come on, not again! God I'm getting tired of these guys.
Anyhow, if you see it pop up again, please run the IE dev tools (F12) and try to isolate the code for the ad server that's spewing this garbage. Voivefive doesn't try to hide, so it will show up as voicefive.com in the loaded ad code. I've been searching for a bit this morning but I haven't been able to trigger it.
