Hi
I have just received an email pasted below it took a long time to download but worked eventually.Good luck!
This Information Applies to:
ZoneAlarm with Antivirus
ZoneAlarm Security Suite
Summary:
My ZoneAlarm antivirus won't update, or gives an error when updating
Solution:
If you get an error when trying to update your ZoneAlarm antivirus:
Click Start -> Find or Search -> type VET_MODULES.TXT
The file should be located in the \System32\ZoneLabs folder
Right-click on the file and Delete the file
Try to update the antivirus again
NOTE - If you get an error when deleting the file, you may need to reboot
into Safe
Mode in order to delete the file.

If you look further down the board you will see that a few people have this problem today, so I guess there is something wrong with the Zone Alarm update system...
My advice: try updating again tomorrow, if files are downloaded/received leave them (do not open) till the definitions are updated
