I constantly get calls from  A Rep, claiming to be working for  Windows - from London, England, He said my computer was hacked into, and he wanted me to get on my comuter so he can walk me thru to correct this situation.  I asked him to give me the number of Windows in Canada before I adhere to his request.  This is the numberr he gave 1-480-409-1794.  I think this was a hoax.
