This is another one of those "Windows Help Centre" scam places that claims they have magically detected a virus on your computer and that you are getting hacked.  They will then try to get you on your computer and follow their instructions which is what actually screws up your computer and then have you pay them to "fix" it.

They keep spoofing different numbers to call from - really getting tired of this sh*t.  And the sad thing is that it will be some old retiree who is not very tech savvy that they're preying on and will fall for this crap.  Wish the police would do something about these a-holes.
