In case anyone else has this issue I wanted to post and update.
Once we were able to get rid of the strange zc-Install_999 folder and files the site was able to be installed in root.
We did run into another issue. The prices from the old database were way way off. The db turned out to be fine.
The resolution was found in the /images/ directory.
There were about 16 .php files within that directory. When viewing they varied in content but all were either complete redirect to adult type websites or they were connection files to other sites of that nature or warez sites.
Checking the images folder is always a good idea. Sometimes its the silly things we over look.
Thanks again Dr. Byte for your help yesterday. Much appreciated.
