Seemingly authentic. Was able to read back to me my Computer ID number. They asked me to navigate to my Admin tools, and verify that I had eight warnings or errors from today, and eleven from yesterday. I am (was) a computer admin, and there were only two from today (valid ones, at that) and the computer was turned off yesterday. They assured me that this virus continues to infect my computer even when it is turned off. I finally hung up on them. My suggestion is that you don't talk to these people but make sure that your virus and trojan software is up to date, download all patches, and run a complete scan on your computer. Something is fishy. DO NOT run any programs or applications that they may send you, and DO NOT tell your browser to accept cookies from any site they recommend. STICK WITH Norton, AVG, or one of the other major players.
