Confused and ticked off

[Don in VT]

I am selling our ZR1 so I went to the link and page that has the form to fill out to get the car sold. When I clicked on the link to the form I was presented with an ad from H &R Block that blocked the link to the form to sell the car. I have been running into this scam a lot lately and it really ticks me off. All I want to do is sell the car and the stupid pop up adds prevent that. I am off the the other forum to see if I have better luck.

Thanks a bunch.
