Problem: The scan has detected some potential problems in these files. First scroll down through the code listed out after the list of links, this is the code returned by the request for the URL you entered and check for any problems. Next, these link(s) will open the individual URL(s) in this tool, check through the code that is returned, compare the code being returned to a know clean copy, etc.
