Resolved!
Thank you for your kind and quick reply.
Deleting SlimStat folder did the trick.
I'll remember backdoor if goof ever happens again.
Extra notes:
I could not follow through right away because it turned I did not have permission to FTP delete. Host support would not help because my domain is under someone else's account, a web developer that helped me get started. But he and I could not connect until Monday. NOTE TO OTHERS: Get clear access to Host support team regarding your own domain! My FTP username originally had full permission. I've deleted in the past but something went bump since then. My FTP username/permissions had to be recreated. ***Having access to Host support would have had my site up in hours instead of 3-1/3 days down ***
