My cousin received a message today that her computer was infected. She called and they never identified themselves but wanted to remotely access her computer. She called me because she was not comfortable with that. Glad she did. I called the number and determined quickly this was NOT Microsoft!!!!! Do NOT call these people, this is a scam. I called back after they hung up on me and the line was busy, but when I called from a different number I got a gentleman immediately, but when I asked him to identify he hung up again, then tried calling from that same number an the line was...you guessed it, BUSY!!!
