Disappearing Icon fun again!

Win xp sp2/i.e. 6 outlook express  NISS 2009 VER. 16.0.0.125 (via reinstall/tech)

 

I'm back !!!  can't belive this!!

                 everything was terrific for this past week-1/2...after receiving 16.7.2.10 -crashing, etc.  Norton tech did a remote and installed the above ...

                Suddenly just now i noticed the task bar icon was gone !!!

                I know this means the program is not protecting my computer - did a restart and it's back (for how long?!)  this is what was happening (among other 'things' when i was updated to 16.7.2.10)

               Only thing i did this a.m. was to do a Windows Root certif update which went smoothly - restarted computer.

               Have not added/removed anything..

               went to 'run/services/msc. - Norton showing as ''started/manual'  if that's any clue - .

               Any ideas ?  thanks in advance.......Edythe
