While looking up a reverse call number there were suddenly flashing lights and sirens and a voice telling me the computer was compromised, to ring this number and not turn the computer off. I did try to turn off the computer without success and I did ring the number but the reception was bad and there was a lot of backgropund noise and without giving any information i rang off. I have since turned off the computer and turned it on without any problem. I have also had a return call from0420 112 492which is also a scam.

probably a tech support scam
