I often get the above Norton warning. It tells me that there has been an unexpected change and gives me three options. I select the middle one which says scan if it unexpected - so Norton 2001 scans, finds nothing and I resume. Does anyone know why I get this. and is there any way of avoiding it. I find that Symantec isolate themselves from their users even if we have paid up to date! I cannot find a way of asking them. I have tried their website feedback but get no reply.
