Please Help! My Norton Internet Security 2010 does not work!

Hello everybody,

 

I registered to this forum because I desparately need help.

 

Beginning around several months ago, my Norton Internet Security has not worked normally.

 

Everytime I powered on my computer the small icon of Norton Internet Security disappeared at the lower right corner of my XP windows, the Norton Internet Secuirty would not response even I click it from the program list many times, the Control Panel of Norton Internet Security just would not pop up!.

 

However, it might work sometimes. Especially after I erased all the browsing history (cookie, tempoary internet file...etc)  of the IE, it would resume normal intermittently for 1 or 2 days.

 

I have updated the whole software and changed the AutoEnd Tasks to 1 but the problem can't be resolved.

 

It really makes me depressing and drives me crazy.

 

Could any expert here advise how I can solve the problem ?

 

Many Many Thanks.
