What is going on??? When I click on a google link, it takes me to a shopping or ad site?

Let’s say I search for the benefits of moist vs dry heat and one link is this: http://arthritis.about.com/od/assistivedevicesgadgets/tp/heatpad.htm – 24k . When I click on it, this is the page that pops up: http://ww1.glimpse.com/search?query=moist%20heat&cm_mmc=miva-glimpseww1miva-8B866329-FB1A-479E-8F82–3CB117091479_-moist%20heat .

Clicking on a link for an amazon product ( www.amazon.com/Moist-Heat-Therapy-Warming-Neck/dp/B0000ZH3G4 ) takes me (after a long moment) to this site: http://www1.bottomdollar.com/search.php/form_keyword=moist%20heat%20pad/skd=1/mode=bottomdollar_miva_hb

This is happening with almost everything I search. It just started yesterday.

Is anyone else having this problem? Does anyone know what it is and what to do about it?
