I am seeing constant disk activity on my system.
Seems to go for a half hour in each hour.
Activity is so high that everything on my system including the clock stops updating/responding.
After the disk activity subsides, I list the files that have been recently updated.
In each case, the last file updated is IAMDB.RDB.
The only way to stop this activity is to unload ZoneAlarm.

Operating System:Windows XP Home Edition
Software Version:6.5
Product Name:ZoneAlarm Pro
