:?: I am experiencing a problem when I go to the internet (does not happen unless I am on the internet). At random times and for no apparent reason, my system will shut off and then retart. I have Windows XP SP2 / cable modem. I have Norton Professional / Adaware & Spybot and none are able to detect a virus that may be causing this. I am being told that this is probably a symptom from a virus of some type. Has anyone else experienced this and any ideas on what I can do to correct it.
