Yesterday morning I installed a replacement DVDR. On restarting the computer I was told the computer was updating. After a couple of hours I realized it was in a loop during restart, (the same screen flashing up, then going blank. Using my Ipad I searched and was told to make sure my computer was on line and then restart in safe mode. I got a trouble shooting screen which I proceeded with. When W10 started again everything had changed. Only Microsoft options were available and my old version of Office was gone. Outlook was gone so my important emails in Outlook folders had gone. I am an older computer user, a pensioner, who can't afford to buy from the cloud. I am the only one this has happened to? Or is this some form of ransom-ware?
