I've been having this problem for several days. NIS seems to be working just fine and the all of the sudden the Norton icon disappears and I no longer have protection. I uninstalled and reinstalled twice (once in safe mode) and it will work fine for a few hours then I get the same thing happening. I DO NOT get any error messages whatsoever - NIS just seems to stop working for no apparent reason. I can restart it thru services.msc but it will only work for a few minutes and then it crashes again.
When NIS is running everything seems just fine. I can do scans, updates etc.
I am running Windows XP and SP2.
Can anyone help?
