877-477-1515

Called them from a Mozilla (looking) website for assistance with a FF browser issue.  They eventually connected me to MS Service Group, LLC  to "clean" my computer.  Their number was 877-413-7077.  Asked me to send a check to NY even though they are listed as being in CA.  After I hung up I ran malwarebytes and found 1600 items.  For real.

Their number showed on a search for Firefox telephone support. I talked to these people on 11/3/15 and discovered afterwards they are a fraud. They tried to call me back today (11/5) using phone number 877-413-7077 (also showing fraudulently as a Firefox telephone support line). I hung up. A search of MS Service Group show there are an unusual number of complaints.

My computer froze while teeing to open Dell support and it told me not to reboot,  not to call my regular support only to call this number.  Didn't, re booted and all is well m

Same thing happened to me today

interfering with my pc,.

Computer locked up pop up says call 1-855-977-0605 then wanted money to fix it!

Pop up on my mac claiming to be Microsoft and that spyware was detected on my computer.  This number is supposed to connect to a Microsoft technician.  Scam from India.
