What I have done:
  1.  Turned off all equipment; unplugged and replugged all
cables/connections.
  2.  Followed links in messages as best I could.
  3.  Did a System Restore.  Tried to go back to Sunday June 24; Mon June
25; Tues June 26; in all cases was told restore could not be accomplished.  
Finally did get restore from Wed June 27, but the problem is still occurring.


Malke's first question is:  What did you change?  I made some changes on
last Sunday and Monday, but system will not let me restore that point.

The changes made?  Deleted one AV and added another.  Deleted some old Java
programs and installed new.

Thank you for any advice you can give me.
