I was called by "Windows Operating Systems" telling me I had a virus on my computer.  She asked me to get on my computer and find the virus that they were warned about by my computer. When I said this sounds suspicious, I asked for a number to call them back on.

This was the number given to me, but does not match the number for Windows.
I called Windows OS and they said this scam was happening.

I did not call the number, fearing more calls from scam artists.

I am always getting calls from this number about my comp

Received a call from these folks Aug 22 at 5:54 p.m. He claimed to be from Microsoft Windows. I told him I wasn't interested and hung up. This same person had previously called Aug 13. I told him I wasn't interested and he wouldn't take no for an answer and was very rude. I finally hung up on him. He then called me back 7 more times leaving angry sounding voice mails. Wish I had kept them. Both days I submitted a complaint to the FCC. The first day, all I had on caller ID was "unknown caller." Today he forgot to block the number so I was able to report the number to the FCC.

I was told that she was from Windows and when I was on my computer that some unsecured sites were being accessed and asked to start my computer. I said, "no, I don't think so." She started to say something else and I just said, "no" and hung up. I believe this is a scammer or telemarketer trying to get into my computer.

Have received numerous calls from this number.  Sometimes they block it, sometimes they don't but the calls are always the same content.  They claim to be "Tech Support" from a company which I cannot identify and the caller can never speak clear English.  They claim that I have a virus or malicious activity on my computer.  When I question their authenticity they get very angry and usually hang up on me.
