Caller identified himself as a representative of the security part of Microsoft. Indicated that they had received through their tracking system, a signal that something was going on with my computer, a trojan  was accessing my system and I was in danger of having my  files and personal information hacked. After I asked again as to who he said he represented and how he was able to receive a warning signal about what was going on with my system, and getting a very technically convincing response (my error for believing), he was allowed to (by my pressing the "flag" and R keys at the same time) show me (by remotely controlling the system) the warning red and yellow checks..., during this process there was a power outage and we were disconnected.  I then got very concerned and called Microsoft Customer  Service to inquire about the caller and his actions. I spoke with Clarence and he assured me that Microsoft never makes these kinds of calls, also that this was a phishing scam and I was correct i calling them. He suggested that I report this to the proper authorities and file a complaint with FCC.
