This morning I got a phone call from someone saying he had information that my computer was going to crash soon.  He didn't identify himself, which made me a bit suspicious, but I was curious how far he was going to try to take this scam so I kept listening.   He used a very serious tone and made it sound "urgent" that I go to my computer and do exactly what he says.   I asked him where he was calling from...what company he represented.  He said, "Microsoft Security Office."   I responded with, "I don't believe you.  Please take me off your list."  Then I hung up on him.  Have you received such a phone call?  Apparently it's rather common so the real experts at Microsoft have posted some good advice on their website.  To help you know how to deal with phone and e-mail scams, it's worth taking a few minutes to read Microsoft's suggestions here:  http://www.microsoft.com/security/online-privacy/msname.aspx
