Hello I have wrote a subject on this problem and it was solved but the matter is back after yesterday's update and it is worst.
All my wifi n posts are down with Zone Alarm, I can't do ctrl+ shift + write click this time.
I only could uninstall Zone Alarm to make the PC work.
There was a massage on the little "Z" icon of Zone Alarm like : "ZA is updated, UI inisializing" but no response of the software after a long time (Vista and 7).
I will try to install again ZA today.
