Getting Chrome back to where it was before installing AVG Ultimate

My first question was answered by support, but did not work. I still have HTML coding in the text box in Ebay listing pages. Install did something trying to protect me on the net, but it has changed something I did not want changed. I followed the steps given by support.  Something else must need doing. Any one know what?  I also am getting a notice, after having purchased AVG Ultimate, that I have 28 days left in my trial. I didn't know I was purchasing a trial. Can anyone give me some intelligent info here?  I so far have spent $30 for ultimate aggravation.  I usually get that for free.
