   Correction to what I said - it is not turned on by default. Must
of
 turned it on by accident.  The buttons (options) are

"attempt" (request secure communications but allow unsecure)
 "allow"    (Do not request secure communications allow insecure)
"require"  (Require secure communications do not allow insecure)

 The default is "allow"

   What the saying - "if all else fails read the manual"

  More on the port 500 scans with this thread and others

Got the latest PGP Dekstop Client v7.0 . It has a feature built
into the PGPnet to automatically attempt a secure connection. The
three options are "attemp, allow, require" secure communications.
From the log (sample below ) it appears to use IKE to initiate the
secure connection. It attempted to create an association with every
IP I contacted irregardless of the type of service (http,imap). It
is turned on by default installation but can be turned off unless
its locked by an corporate adminitrators kit (laptops).  Could be
an explanation to the sudden increase in port 500 detections
