To everyone who gets calls from these numbers - they are a complete and total scam.  Windows would never call you personnally.  I would be worried they want to get all of your personal info off of your computer even more than what they want to charge you.  yes, all windows event viewer and other logs will contain harmless errors.  They use this to gain favor and trust with you.  Just tell them you are calling enforcement on them and report them!  This is one of a few different numbers they call from.  They ARE A SCAM!!!!

2nd time I received a call from this number.  Thick Indian accent.  Reported to my security provider.

Do not return or answer the call.  I had computer checked with security co.  Ran deep scans. a hoax

I have full confidence in my securityt firm they are paid to protect my computernot some ghost out of

nowhere with an english speaking deficency.

Just got another call from this number. I reported previously that I did not answer, and again I did not. However, my voice mail answered and the person must not have realized it. There is a lot of noise, almost like an airport terminal or busy place. Then a voice with a heavy Indian OR African accent says my maiden name, spells it out, and keeps saying "hello?" Obviously it was the same thing I am reading from others.Thanks for letting me know it is a scam artist!

Just got a call from this number at my place of business.  He had a strong East Indian accent and thought this was my home.  Said he was calling from Microsoft Windows and that my computer was infected.  I told him he would need to talk to our IT guy and he hung up.  Knew my maiden and married name and where I worked.  Could he have gotten it off Facebook?

My wife fell for this scam and it ended up costing us about $200.  They want remote control of your computer and act like they are doing some kind of repair/scan.  DO NOT allow them access to your computer!!!!!!  BEWARE!
