zonealarm controls computer very strictly from my experience. BUt for my new laptop which doesn't have zonealarm, after installation of latest update, it got hanged up after I was trying to turned it off because sysfader.exe is not rsponding. sysfader.exe can not be ended by task manager. could this be an evidence of windows update problem?
btw, I cannot reproduce his problem again, so i diabled "fade effect" from dispay/apperence/effect.
can u tell us more about it?
