Non-detection of AdChoices and DNSUnlocker

I am having pop-ups constantly from these two adwares which AVG is not stopping for some reason.

How do I get rid of these?  When I Google them, all I get is a bunch of Adware Removal sites wanting me to download their removal tool.  Too suspect to do that.

please help!!
