Several times now, after starting my system I get the message that my system is at risk and find that something has turned off the antivirus part of NIS 2011 having just upgraded from 2010 I find this a bit unusual! I have been using NIS for the last 5 years with only one similar problem a few years ago! Any ideas what might be stopping the service? Could it be a Trojan?? Aren't we supposed to be protected from these things, when we pay our money ??
