This morning (September 28th) Sophos has decided that SUPER contains the virus Mal/Packer
(http://www.sophos.com/security/analyses/malpacker.html). 

"Mal/Packer is a program that has been packed with a protection system typically used by malware authors."

  Are the executables for SUPER compressed some how that might be triggering the over-zealous Sophos, or is this a false positive?
