PGP Causing Slowness Deleting Files

I was experiencing long delays when attempting to delete files from my laptop or external USB drives.  For example, deleting a 1.5 GB file would start a continually rotating flood bar of deleting.  It would run for 30 minutes or more before I would give up and click the cancel bar in the dialog window.

The canceling would also present a never ending flood bar lasting 15 minutes or more.  After doing some research regarding an early Vista problem with file moves and deletions I looked at several configurations but could not find the problem.

Finally realized during the installation of PGP desktop I had enabled a secure delete (shred) feature.  When I disabled the shred feature, my never ending delete processes went away.
