Potential adware at btrill.com

I’m using Open DNS and when I look at my blocked domains report, it shows lots of entries for this domain - see below. Open DNS identifies it as AdWare, but Avast doesn’t find it. Can anyone help?

Blocked domains
geo-um.btrll.com
vast.bp38xxxxx.btrll.com
pix.btrll.com
shim.btrll.com
segs.btrll.com

Thanks
Pete

If OpenDNS block them, then i guess your avast never see them as they are blocked before they reach your computer. And yes they are advertisement domains

You may need to turn off OpenDNS to test

Anyway if you have something you think avast should block

We do not block adware domains, only the (PE) files that are downloaded from them.

Well btrll.com is also blocked by the firefox uBlock Origin add-on.

Doesn’t the fact that numerous attempts from my computer TO access the brill.com website indicate my computer is infected?

Not necessarily many/most sites that you browse access 3rd party sites and some of those will be accessing btrll.com. My image comes from Yahoo, so there are many legitimate sites accessing it.
