How To: Fix Zone Alarm (zclient.exe) High CPU Usage
r3dux | January 7, 2010Think 25% CPU usage is unacceptable for a software firewall? You’d be right.
Steps to fix:
- Ctrl + Shift + Right Click on Zone Alarm icon in the system tray and select Set debug level from the pop-up menu
- Set Debug Level to Off by clicking the appropriate radio button in the Set debug level window
- Click [OK]
- Restart Zone Alarm (i.e. quit then restart it)
Works on:
ZoneAlarm version:9.1.007.002
TrueVector version:9.1.007.002
Feel free to delete the stupendous amount of logging dirge left behind by Zone Alarm’s “writing phase” in C:\Windows\Internet Logs while you’re at it.
