Who called from 2108240171

This number called and tried to get me to turn on my computer so he could talk me through a malicious spyware removal.

They would definitely have gotten people to do this.  Then they would have had their personal information.

It seems my computer got infected after I tried to download some pop songs for my daughter. The most aggressive software is Hotshield, plus some other mp4 download softwares. Then I saw this phone number after a month I found funny things with my laptop. Are there related? If so, that's really a scam. Disgusting! I'd  rather reinstall then pay them.

Microsoft never ever calls anyone to tell them about malicious viruses or anything else that may be related to your computer.  If you gave them information, time to scrub it clean and check to make sure nothing funny is going on with your finances.  These guys are a joke.

These numbers are not legit. Same guy called me 3 times in 3 minutes from 3 different States.

When I answered, nobody answered.
I do not like being pestered, and having my schedule disrupted by nuisance phone calls.
