I installed and ran Anti-Malware by GOTMLS.net. It reported various files in this directory that, I believe, W3 Total Cache created are "known risks."
The directory is /wp-content/cache/page_enhanced/www.johnrothra.com/...
My URL: http://www.johnrothra.com
All the reported "risk" locations end in _index.html, e.g., .../public_html/wp-content/cache/page_enhanced/www.johnrothra.com/1X/_index.html
Do I need to keep these cached files?
