A new program recently appeared in Program Control with Super Trust Level.
The program is listed as "5704AB8}" (with trailing curly bracket, but without the quotes).
The Entry Detail tab has the following:
Product name = (empty, nothing appears)
File name = 5704AB8}
Last policy update = Not applicable
Version = (empty, nothing appears)
Last modified date = [invalid date] - that's exactly what it says in the field
File size = 0KB

This appears on both my tower and laptop PCs.
I've reset access and server to "ask" but it resets itself to "allow" without asking.
When I reset to "ask" a "System Programs" pop-up warns me that applying custom settings may cause problems...
I tried a full system file search and Windows XP Pro Service Pack 2 (all updates) cannot find any file with this name.

Any advice would be appreciated.

Operating System:Windows XP Pro
Product Name:ZoneAlarm Pro
Software Version:
