They are Scammers. Beware.

They have a pop  up on my computer that won't let me exit out:(

They have pop ups on the Internet also that won't let you exit out

restart your computer or hit the keys: Ctrl, Alt, Del then go to Start Task Manager then delete one Window Explorer Web Page.

Had it on my computer also.  Kind of did what Sammy suggested.  Computer seems to work OK now.

Malwarebytes and Microsoft security essentials did not catch it.  Using those two this was the first problem I had in a very long time.

Same as everyone else. Came up on a popup, even though I have popup blockers, and warned about system 86 error. Had to start task manager and exit browser. Obvious scam page. Do not call.

Random pop up that wanted me to call them. Obvious scammers. Just restarted my computer and everything works fine.

Same thing with me. I've actually contacted Microsoft to report this and the told me DO NOT LET  THEM IN MY COMPUTER. Taking my computer to people that will clean out the spam crap

Computer scam do not call them back just unplug your computer and restart it. Warn others they are useing a spoof number also report this number.
