Thanks Phil,
sounds like my friend has somehow met up with a scammer and her computer has been infected.  Luckily she quickly turned it off, but as its crashed I may have to do a reinstall Windows for her as I don't know what her machine has been infected with.
Thanks for the info.

HI i work in a troubleshooting call centre , i have had many calls today, about a company calling customer and say they are Microsoft and entering computer and changing and infecting computer with many things,, PLEASE IF YOU GET A CALL FROM THIS NUMBER (02) 9191 6514,, PLEASE HANG UP THIS IS A SCAM,, note companies like Microsoft do not call customers.

Jenny from Windows User called, saying she was sent an error report from our system and wanted me to turn my computer on so she could show me our infected items.
(02) 9191 6514.

I can't stress enough how dodgy this is. Please Do NOT trust random callers, despite who they say they are!

Windows don't have our contact details, let-alone call us like this. They don't fix our PC's "infections" anyway.

A female indian caller phoned a friend of mine earlier today stating she was calling from Microsoft in relation to a potential problem that they had identified with my friends computer. The computer has subsequently crashed and I am trying to identify if the caller was genuine or if she was a scammer.

Hi, I just received a call from the same people. A woman told me my computer had errors and then asked if I had a computer (??) I asked who she was and where she was from. Her name was Sonia from Windows in Sydney. I put my partner on the phone because she could barely speak English and he can understand broken English better than I can (I'm hopeless with it), then after a few minutes Sonia put my partner onto a guy called Edward, supposedly the tech support person. I told Adam to tell them to hang on, and while they were hanging on, Adam looked up some things on google. I took the phone and asked Edward if we could call them back. He gave me the number (02) 9191 6514 (I don't have number display). Adam found the scam on google and I found this site by googling the number. Adam is currently watching a youtube video about recording the call, I'm unsure whether to call back and record them as they will probably know we're onto them. Will write again if we do or find out anything further.

Got a call from William Smith (Dodgy Already) from Windows/microsoft to fix my computor problems, was very suss, I asked for a contact No and quickly googled it finding this page. Told them I will get my computor Tech to call them back and look into the problem, where they were very quick to say OK and good Bye!
