When ScanMail cannot successfully clean a file, it labels the file "uncleanable" and performs the user-configured action for uncleanable files. The default action is "Replace with text/file". ScanMail records all viruses/malware events and associated courses of action in the log file.
Some common reasons why ScanMail cannot perform the clean action are as follows:
  • The file contains a Trojan, worm, or other executable program. To stop an executable from executing, ScanMail must completely remove it.
  • ScanMail does not support the compression format used to compress the file. The scan engine only cleans files compressed using pkzip and only when the infection is in the first layer of compression.
  • An unexpected problem prevents ScanMail from cleaning.
