Thank you for your detailed instruction and time. Somehow I managed to solve the problem already.
I hadn't been able to download updates separately from Microsoft Download center  but finally managed to do so with IE.
Looks lie it's the only browser that can do it.  The weird thing  is all the updates msu files have a certificate expired in 2011.
 Then I just installed those updates one by one and everything went ok.

Did this solve your problem?

Sorry this didn't help.

Roll up your sleeves & cross your fingers...

 

[You will want to print these instructions for offline reference. You must complete all of the steps in one (1) uninterrupted session - allow a minimum of two hours.  If a Step says to reboot, reboot! ]

 

1. Right-click on the following link to download the Norton Removal Tool, saving it to your desktop:  ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

 

2. Close all open applications (i.e., anything with an icon on the taskbar).

 

3. After making certain you have a copy of your Product Key handy, uninstall Norton Internet Security and then LiveUpdate as well as any Norton Add-ons via Start | Control Panel | Programs | Programs and Features.

 

4. IMPORTANT! => Make certain that the Windows Firewall is enbled immediately after rebooting! [Should happen automatically but I want you to check.]

 

NB: You're "working without a net" now: Don't to ANYTHING else online (e.g., browsing; reading email; chatting) until you've completed Step #7 below!

 

5. Right-click on the file you saved in Step #1 above and select Run as Administrator. to run the utility. Don't TOUCH your keyboard until the run completes, then reboot.

 

6. Do a clean install of Norton Internet Security v19.x (using your Product ID, if need be) & reboot; cf. https://support.norton.com/sp/en/us/home/current/solutions/kb20090708112600EN_EndUserProfile_en_us

NOTE: Do NOT enable or install any Norton Add-ons or toolbars (e.g., Norton Anti-Phishing) just yet.

 

7. Manually and repeatedly run (Norton) LiveUpdate until you get a "no more updates" prompt.

 

8. Download/run the appropriate scripts from the following Trusted Source (my colleague IE MVP Kai Schätzl): http://iefaq.info/index.php?action=artikel&cat=42&id=133&artlang=en

 

   Note => The scripts are good for IE9 & IE10, too!

 

Tip: The file named ie8-rereg.all.zip contains both of the scripts below (plus a third one you will NOT use).

 

9a. Close all open applications (i.e., anything with an icon on the taskbar) then double-click on the file named ie8-rereg.32on64.cmd to run the script.

 

9b. Close all open applications (i.e., anything with an icon on the taskbar) then double-click on the file named ie8-rereg.64on64.cmd to run that script then reboot.

 

10. Re-assert Internet Explorer as the default Browser in the CUSTOM (<=important!) section of Set Program Access and Computer Defaults. [1]

 

11a. Right-click on the following link and SAVE the download to your desktop: http://www.slipstick.com/problems/reg/chromehtml.reg [2]

 

11b. Double-click on the file you saved in #11a above & accept the prompt to MERGE the data with the Registry.

 

12. Open Internet Explorer (only!) to http://support.microsoft.com/kb/923737 [ignore any DOES NOT APPLY warnings as well as the APPLIES TO section] & run the Fix It.

 

    Note=> For optimal results, check the Delete personal settings option.

 

13a. Open Internet Explorer (only!) to http://support.microsoft.com/kb/910336 [ignore the title & Symptoms].

 

13b. IMPORTANT! => Dismiss/close the Windows Update troubleshooter "pop-up!" - then...

 

13c. Ignoring any "Not recommended" or similar warnings, run Fix It 50202 in DEFAULT and then AGGRESSIVE modes. [3]

 

14. Reboot one last time then run a manual check for updates & see if all security-related updates offered (if any) will successfully install. Follow all prompts.

15. Reply to this post with a status report.

 

Good luck!

[1] After we've finished this thread, feel free to reassert Firefox or Chrome as your default if you wish.

[3] Full Disclosure: Running the Fix It in AGGRESSIVE mode will delete your Update History but not the list of Installed Updates.
