All depends on a few things. Immediately that spring to mind is... 1. How long have you been running Zonealarm? 2. Do you have a Hardware firewall/router? 3. Is windows firewall also enabled? muf
If you use ZoneAlarm , it will automatically disable Windows Firewall . If you somehow manage to turn it on , you should not do it because having more that one firewall/antivirus will result in confict between the programs and possible crash . It depends , it is good because hackers don't want your computer
