Norton Identify Safe extension disappeared in Chrome 26

Hi,
the Norton toolbar and extension disappeared recently and they are not even listed in the Extensions list of Google Chrome.
I don't remember why or when it happened but it was during February-March.

 

I have :
Norton 360 v 20.3.0.36 with latest Live Updates.
Google Chrome Version 26.0.1410.43 m. (latest)
Windows 7 Ultimate 64-bit.


Is there a way to reinstall the extension on Google Chrome or to fix this?
I think you may end up suggesting me to reinstall Norton or Google Chrome but I prefer not to do it since I don't want to set again the exclusion list in Norton and reconfigure it and I don't want to reinstall all of the extensions of Google Chrome I have.

NB : The Identify Safe toolbar is working on IE 10.


Thanks.
