Does ZoneAlarm slow down a computer?
ZoneAlarm is optimized to deliver a minimal impact on the performance of your PC during normal operations. In most cases, you won’t even know your PC is being protected by ZoneAlarm. For users of ZoneAlarm Antivirus or our award-winning ZoneAlarm Internet Security Suite, you may notice a reduced response time while ZoneAlarm is conducting a scan of your PC for viruses or other malware. If this is inconvenient, you can always stop the scan and reschedule for a time that the PC is not likely to be running other applications.
