Yes, it seems that you have received a "cold call". I'm glad that you did not fall for it.  :emotion-21:  We have discussed these on this forum in the past. Articles that include links to additional information: [URL]
I had a strange call today; the caller claimed to be from "Microsoft Windows Tech Support", but the call originated from London, U.K. He said my computer (old Dell Latitude D600 Laptop) was having problems; he would help fix them. Would I please open the computer while he was on the telephone. He would hold my hands in fixing the problems. The whole thing sounded strange and unsafe. I had heard of such calls, and that the purpose was to cause some damage, viral or otherwise, and then to offer repair service, at a price of course. I fended him off, but he called again the next day. However, I haven't opened the computer with the caller on the phone. Does anyone know what this could be all about? My computer does have occasional problems, nothing unusual though.
Phishing?
