Just had a major computer crash, due to scam program called Security Tool. I had to have a professional to get rid of it,for which I was grateful. However, for them to backup existing computer, they had to format several of my drives. I have,as you can imagine,lost a good deal of my programs, settings,etc,which I can, I hope, replace. Main difficulty is that I have lost all my email contact addresses. Does anyone have an idea about how to retrieve them? I did manage to archive a lot of in-box emails through gmail, and if no-one has a brilliant idea, I will just have to go through ALL of them and pick out the addresses. Also, I can't find a way to recover any sent emails Any advice?
