Hi. There is a scam on your computer where the screen turns red and warns u to not turn off your computer or delete the msg or you could lose everything on your computer.
Somewhere in the msg Microsoft is mentioned and a 1-800 # is given for u to call for repair. The tech person is foreign and if you let them into your computer thru Citrix they will show you a screen with all the invaders inside your computer then try to sell u repair software at a cost of over $2000.
If u refuse, they plant a virus and lock u out of your computer. I had to take mine in to be repaired and to be able to get back in. Money out of my pocket. The repair guy said he had someone come in that was so frightened by one of these scams that he threw his computer in a fire to get rid of the threat.
So do not fall for these scams. Microsoft or the FBI or police, etc. will not make these threats.
