I keep getting calls from this number that turns out is not even an valid U.S. are code. It shows up as a country code for Sierra Leone. They call stating they are from Microsoft and that they recieved an error report from my computer and ask me to download a program that will let them have real time view of my computer. I of coarse did not download anything from them. The program they ask you to down load is a valid program to allow someone to view you computer. But of coarse these people are not from microsoft much less Microsoft would not call and ask you to do that especially since Windows already has such software. I have asked them to remove my number but of coarse they continue to call almost daily. I did file a complaint with the FTC.
