Scam calls saying computer is infected

I have been getting calls from someone claiming they are from Dell and sometimes they say
"Windows Tech Support" The most recent was today less than an hour ago. The idiot told me he
could prove he was from Dell. I told him to prove it he said he could tell me my service tag. I told him
That does not prove it. I stated telling him to e-mail me proving he was from Dell. He would not even let me finish explaining and he said how am I going to help through e-mail. I told the knuckle head to let me explain then talk. I told him to e-mail me with his Dell employee info. He said no we are not authorized to do that. I told him well that right there proves you are not from Dell. Then he started cussing me and saying he did not like me bla bla bla I laughed he mocked me laughing that went on a few minutes then I hung up. I know it's a good idea to not answer or hand up when you suspect it's a scam. But my Dell laptop does have some issues and it is under warranty and I have been in contact with Dell so at first I thought he was from Dell. But when he started telling me my computer was sending warnings I said hold on sir. I should have just hung up. But I am trying to figure out how do these scammers get my info. To me this is serious. I was having this issue a few weeks ago and I have used the Dell site to report it and also I reported it to the Federal Trade and put my # the Federal no call list. I just want to know how do these people get my info? Could this be a tech from Dell doing this on the side that got his hands on people's info? The number was 1-800-625-9896. I call it back it tell's me it's no longer in service so that means they are spoofing numbers. The tech was named Alex. I will report this again and this time I have his number. Maybe someone can explain how this is happening. Oh they are calling on my cell number. You can check this out I made it a few weeks ago it is funny.

I have told them I used a mac. Also told them I used Linux. Next time I am going to tell them I still use Windows 98.

Tell them you have a Mac, but it is running Linux within a virtual machine!

A moderator at the forum of my preferred Linux distro recounted this some years ago:

I just had a phone call from a "Microsoft technical service" technician, with a really thick accent, who was calling to let me know that my computer was "infected, and had been sending them notices", and that my (Linux) machine is "very, very dangerous and he wanted to help me fix it". I am busy this afternoon, but I decided this might be fun, so I played really dumb and let them walk me through their script. Of course, I was not doing what they asked as it was not really applicable to a Linux box When they would - finally- walk me to the point where a Windows run dialog would otherwise open, they would pass me to a "supervisor" to walk me through the rest of the "repair". During that hand off, I would suddenly go stupid again, and I would magically no longer have the run dialog on my "screen" and would have no idea what he was talking about. About the third time around the loop I was growing weary of toying with them, so I slowly, but monotonically, increased my competence. About the time I reached the level of an entry level engineer they realized I had been screwing with them. It was a complete waste of time and I wound up being called a Mother F***** by a guy with a humorously bad accent. I guess I am done for the week. Time for a beer and a smile.
