Ahah I'm glad it was easy ; it's always better to have a software problem than a hardware one
OK so I uninstalled ZoneAlarm using the link you provided, then I tried to uninstall all that virtualization shit (daemoon tool, the one I used under XP, didn't work with 7 so I tried a lot of other free alternatives -_-' Never thought that will lead me to problems) using the control panel, and finally I uninstall that last shit using your link.
So far everything seems fine, but we will really know after a full day.
PS : I don't get why you thank me, Shouldn't I be the one to than you ? XD
RePS : It's gonna be the first time after I don't use ZoneAlarm (it's my firewall for about 7 years now, since my very first computer). Can I trust that Windows 7 firewall that seems to have replaced zonealarm ?
