I can't get rid of "pricechop" extensions.

I went through all the steps in the guide (http://malwaretips.com/blogs/remove-price-chop-virus/#uninstall) to get rid of pricechop, but its still coming back. I did run the adwcleaner scan, but I didn't know I needed to keep the log. The FRST logs are attached, as is a screen shot of the extentions that keep coming back.

Also, before I found the guide above I ran Ad-Aware antivirus and Spybot S&D, to no avail.
