I went to a download site I do not usually go to-- got a Audio and visual constant warning saying it was from Microsoft and that I was in getting my bank, email, facebook details accessed, and to urgently call the no 1800 213 922 to get Microsoft to help stop the theft. I could not close this warning and even shut down my computer. when I restarted the computer, it was still there. So I called the no above, He said he could help me stop the possible theft by allowing him access to my computer. This sent alarm bells through me. So I said I needed to think about it and hung up.. Called my awesome brother and he helped me get rid of the constant audio and visual warning, through accessing my own computer. I am pretty sure this is a scam, as my brother said Microsoft would not ask for access to my computer ??
