Yes site contains a inline script leading to PHP:Shell-BB[Trj] residing at htxp://www.sh3ll.org/egy.zip which is correctly blocked by avast web shield see screenshot.
That is mentioned there, but here I get in all instances all a HTTP/1.1 404 Not Found
→ Sh3LL dot org inurl c99.txt inurl c99.php inurl r57.txt inurl r57.php inurl locus.txt inurl locus.php etc.,
see: http://urlquery.net/report.php?id=71216
But as BitdefenderTrafficLight blocks it also, this might be a correct detection,
The requested URL /Sh3LL dot org inurl c99.txt inurl c99.php inurl r57.txt inurl r57.php inurl locus.txt inurl locus.php inurl c100.txt inurl c100.php_files/saved_resource.htm was not found on this server Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.
