The calls originate in India. They can't be stopped. You can protect yourself with a call blocker. Also don't pick up on calls you do not recognize. For some reason they use 304 area code for scamming.
Caller claims he is from Microsoft doing "routine service" on Windows computers. After stringing him along for a bit, I got him to admit he was doing this routine service on every Windows computer in the world!!! He wanted me to be sitting in front of my computer so he could "check" when my Windows software warranty would expire. Obviously, I did not oblige and told him to lose the number. VERY heavy Indian accent, so assuming coming from a call center somewhere. I asked him what I was going to owe him or what he would want from me for this service. He said "nothing". I asked him how he knew I had a Windows computer. No response. I asked him WHICH computer he wanted me to sit in front of. All he could do was ask how many I had. Clearly he wanted to do some sort of remote access. Beware!! I really hope no one falls for this.
Just got this call. Same story as above, wanted to fix my Microsoft windows, asked him since I bought my computer at Microsoft Store why I shouldn't just go back there (not true for 3 of my computers). Asked him if I could call him right back, he gave me 201-732-9610 phone number, which explains why he told me he was in NJ when 304 is area code for West Virginia which came up on my caller I.D. Asked him repeatedly why it says on the Microsoft website I should not accept calls like this, and he said this was urgent. Very persistent. Am reporting both numbers to the Missouri Attorney General's office. Definitely a scam. They will try and hack and do no good. Heavy Indian accent. He is trying to tell you to give him remote access to your computer. I have done this before with my security firm, and that is exactly what he is trying to do. VERY persistent. Do not fall for it.
