This is a scam Rated 1 out of 5 stars
I downloaded pdfescape a while back and was very pleased with it.
I do volunteer work on web sites for several local youth sporting organizations, I started receiving complaints that some links on the web site were not going to the correct locations. I looked and they were going to PDFescape. I figured no big deal, I changed the links and uploaded again, looked the web site over and the links I changed were okay, but the other links that were good were now pointing to PDFescape. I had to use the hosting server software to change the links. This is true on all the web sites that I worked on.
DO NOT DOWNLOAD THIS SOFTWARE.
