Update 15:30, 09/07/08
Checkpoint is now advising Zone Alarm users of three fix options, which will get them back up and running until the issue is fully resolved.
It's all here.
PUNTERS who use the ZoneAlarm security package might not want to install MS update KB951748.
According to several news groups, the first thing you will notice after running the update is that your internet connection dies as KB951748 made changes to the networking files that Zonealarm doesn't like. It then decides to block everything just to be safe.
You can get around the problem by setting the Internet Zone Security permission slider from high to medium and that will give you your connection back but that is not really a good idea if you want high security.
Sniffing around the forums we found similar advice although, apparently, the best bet is to reset the ZoneAlarm database.
No word has come from Microsoft or ZoneAlarm yet on the problem which appears to be caused by the update not liking the different file sizes and checksums.
It might be a bad idea to install KB951748 until after either of the companies releases some more concrete information. µ
