This evening I received a call from someone I couldn't understand and he said he was from Windows and someone was trying to hack my computer from the internet. Caller ID didn't give a phone number--only an Unknown Caller and Private Number. Has anyone else had a call like this. I hung up and the guy called again--and again said he was from Windows, etc. I told him I would call the company that I bought my computer from and hung up. I believe this is a scam but hadn't heard anything about this from anyone else.
