Pop up while using RIU

The last couple of days I've been getting the following pop-up warning while on RIU.
I have not seen it while on other web sites.

The current webpage is trying to open a site in your trusted sites list.
Current site: Drads.net
Trusted Site: res://ieframe.dll

Is this Adware? Spyware? Other?
Anyone have input?

Thanks.

Is anybody in there?

Sorry, Man, I've never seen that, or know anything about it. Are you still getting it?

Not for the last couple of days - thanks for the response.

Sorry I did not reply, it was our old adserver trying to serve ads that were not there

Ok, now I'm getting the following pop-ups everytime I refresh.

http://pop.webfile.com/?epop=true

I am able to turn on the P/U blocker & keep them out, but its the first time I've had to do this.
WTF now?

I'm having the same issue I had to switch to safari and activate the pop-up blocker. I was getting 10-12 windows at a time popping up.
