Update causing HTTPS: problems?

Hello Jondo,
I'm sorry to hear about this. In this case, I request you to repair AVG Protection (http://support.avg.com/SupportArticleView?urlname=How-to-repair-AVG), update (open AVG Internet Security/AVG Free Antivirus > menu > settings > update) it one more time and reboot your computer once. After reboot, please check if you can access your websites with enabled AVG program.
Best regards,
Alok.

XPsp3 Win32 PC, Firefox, AVG Free, 3G internet
AVG just updated 2 days ago & restart my PC (XP Win32).
Now I cannot open HTTPS: web-pages unless I turn off Online Shield in "Settings, Components"
Firefox is always latest.
Any suggestions what might be the problem or how to resolve.

thanks
