Since yesterday, when i'm running my computer, it shutDowns after 5 seconds of running. In order to make it work, i need to press continuously the escape key so the popUp alert who close the computer can dismiss.
When the os is launched, if i let the computer sit without any input, the alert panel appears, and if i don't do anything, my computer shuts down after the alert panel has been shown for 2 seconds. So this is very annoying.
Strangest thing is, that it appeared the same way last year (between october and november), and it disappeared same way it appeared. I have tried to change calendar date and time, but it was unsuccessful.
My question is: What could cause this alert firing ? Can i get a way to catch the $*%* process who send this? Of course i can re-install the OS, but that's out of the question.
I have googled it and it seems that nobody has encountered this. I'm on Lion 10.7.4 and running it on a macBookPro, but last year on snow leopard the same thing occurred. I don't think it's a virus since it should appear on lots of computers, but it seems to appear only on mine.
