This is what the Pop-Up said

Faulting application vsmon.exe, version 7.0.362.0, faulting module msvcrt.dll, version 7.0.2600.2180, fault address 0x000372e3.

After that Zonealarm would freeze and I would not be able to do anything. I would have to manually shut down the computer and start it back up. This normally happens when i leave my computer on all night or for a couple hours. Any help would be appreaciated.

Operating System:Windows XP Home Edition
Software Version:7.0
Product Name:ZoneAlarm (Free)
