I am using Outlook 2003 and ZoneAlarm Suite 6.5.722 on two home networked computers. One began having problems several weeks ago when we got a Window saying Outlook had encountered a problem and needed to be shut down. There was also a ZoneAlarm window that asked to report to ZA what we were doing with the problem occurred (usually nothing or perhaps an automatic Send/Receive). This problem reoccurs every day or so and occasionally there is a window saying say program is trying to access the Contact list. I am and given the option to permit or deny. At times Outlook totally freezes and the program can only be ended with task manager. It takes several attempts to end the task. Now a second computer on my home network is starting to experience the same problem. I suspect a virus or worm, however many virus scans and scans with AdAware have turned up nothing. All definitions are up to date.
