I'm in danger
I decided to have a look on Kerio 4.0.7.
I tryed to install Kerio without desinstalling ZoneAlarm.
The setup alert me of an incompatibility.
I give up. Desinstall ZoneAlarm, Boot and install Kerio 4.0.7.
On the next boot I receive an error message (The service could not be connected or something like this).
avast! freezes (icon stop to swirl).
I manually start the Kerio service and firewall seemed to work.
Each 5 seconds the firewall ask me for rights to access the Internet. I was calm and answering with logic...
Suddenly, the system starts to SHUTDOWN
I have indeed a shortcut on keyboard to do so, but I have to use both hands (Ctlr+Alt+Page down) and my hand was in the mouse!
The shutdown was forced, I lost my work
Next boot, Kerio alert the same service trouble described above.
I GIVE UP!!!
Roxio GoBack save my day again
I know it could be a trouble about ZoneAlarm desinstallation but nothing was alerted or adviced before Kerio start to mess my system. I know this is a good firewall (many high users of avast! forum recommended it in the past). But not for me.
I went back to my beloved ZoneAlarm
