I am travelling on business at the moment, and use Vodafone as my mobile internet provider. Last night I kept getting a pop-up called 'Network Alert'. The message said that there was someone else on the network with the same IP address as my computer and that I should contact my network provider to sort it out. My PC Security centre also told me to re-start my computer about sixty seconds after I turned it on. Is this any way related to that Internet Explorer warning?
Patch available later today
