I am thinking the latter.
My cell phone rang, & it showed "unknown" rather than a picture, name or number. I answered anyway.
It was a foreign-sounding voice who knew my name. He said he was calling in regard to my Windows program. When I asked for more information, he said my XM. I no longer use that system. I told him that but did not identify what Windows system I use now. He kept telling me that my computer had downloaded some files that would damage my computer. I don't think those are the exact words he used, but I can only remember so much. I told him I would check with Norton. His response was that Norton wouldn't detect this.
First of all, I could not understand him. He kept talking, & I kept interrupting to tell him I couldn't understand him. Each time I asked him what company he was with, he would say he was calling about my Windows. He didn't even bother making up a company name.
I finally told him I wanted to talk with someone who could speak English that I could understand. He said he would get his supervisor.
A voice then said he was David. I think it was the same person trying to speak more clearly. I again asked for someone who spoke better English. He said he would speak more slowly.
He asked if my computer was on. I asked which computer. He wanted me to go to the computer, click on start, right click on computer & then click on manage. That's when I hung up, which is what my husband wanted me to do from the beginning.
It had to be a hoax. No legitimate call would have come on my cell phone, as I only register my home phone. I wasted 6 minutes on that call. Why did I even answer?
