Threat: Four On detected.....

For some time I have been getting the following warning: "com.sophos.intercheck: 2012-07-31 13:40:27 -0400 Threat: 'Four On' detected in /private/tmp/xxxxxxxx.$$$"  The warning and related file disappears within moments.  I have been unable to trace the source of this threat, and information on line regarding Four On is sparse.

Any input to help me track this down and remove it will be appreciated.

  • Wow... if you ever get a sample to sit still, please submit it to the Sophos website!

    Can you set on-access scanning to deny access and move threat, to copy it to another folder (one that's excluded from on-access scans) as soon as it's detected?  Then submit the resulting file via our online submission form.

    This is almost certainly an FP, unless somehow something is creating a temporary file repeatedly which contains a Windows virus (not trojan) from 1994....  Once we've got a sample and can see what's going on, we should be able to patch the detection identity quickly.
