They say they are calling from windows because your computer ave problem. They take over your computer and try to sale you protection plan telling you your computer crash now if you dont.

Ils disent  appeler de Windows parce que votre ordinateur a de gros problème. Ils prennent en charge votre ordinateur à distance pour essayer de  vendre un plan de protection en vous disant que votre ordinateur plante maintenant, si vous n'achetez pas.

This is indeed a scam. See the Canadian Anti-Fraud Center. This is one of the most common fraud. If you do get a call from this number or people saying they are calling from Windows or Microsoft and say they have been advised that your computer is infected and they can help cleaning it (or something) then just say : I know this is a scam and it's already been reported. Believe me they will hang up right away and never call you back

Il a  bien infecté mon ordinateur.

It has infected my computer.

I received a call from this # telling me there is a warrant out for my arrest and will proceed with it if I do not call 4089155242 by the end of day. When I tried calling the # it I can get through as no body answers it. It sounds like some kind of a scam.

They called and hung up this a.m.  Checked the area code (here-Google) and found it to be in Vancouver, B.C.
