Tech support scam popup

Number : 18009179841

popup : hxxps://

popup may lock browser, I leave javascript disabled to prevent this so I wouldn't know.
The number is working as of now in skype and firertc, they claim to be microsoft and there is no switchboard so call flooding would be possible.

another popup :

popup : hxxp://
Number : 8882346534. the popup won't show if you visit the link directly, you have to use a typo of youtube. here's a screenshot because I can't attach photos because something went wrong.
It's IYogi btw.
I suspect this one will do a browser lock too as it asks me to enable javascript.
