I was at a conference this past week. The facility had free wifi which I took advantage of. On my last day, I started receiving the following message when starting Safari (and firefox, too, so I guess Safari is not the problem): "Anomalous Behavior Detected -- Request Blocked Your computer was automatically blacklisted (blocked) by the network due to an abnormal amount of activity originating from your connection. It is possible that your computer is infected with a worm and/or virus. Please contact your network administrator for assistance or more information. " Ok, I just figured it was some kind of anamoly caused by using my MBP and the network preferred windows machines. I have now returned home, and I continue to receive this message when I start a browser, whether I am using my WPA-encrypted wireless router or a wired connection. Any idea what I should do?
