I have read about the Mac virus from pirated software. I didn't do that. I just bought this computer a few months ago. I bought the office software for an additional fee. That was the only thing I put on it, uploaded from the disc straight from the Mac store.
The reason I am a bit concerned was I suspect I had been corresponding with a Nigerian "romance" scammer. I certainly didn't send him any money when he asked. (The whole reason I put up with men is for money so sending funds would entirely defeat the purpose

.) No real harm done and it had its amusing aspects. But he did e-mail me a few pics which I had to download. (Probably of some poor guy who has no clue his pic is being used in that way) Since then I have read about PC owners who claim after they broke off correspondence with their scammers, they were sent viruses that forced them to clear off their hard drives. (Actually mine begged me never to contact him again, but I won't go into that here

). Basically then, I don't have to worry because there is no way a simple pic can harm a mac then right?
This is a bit weird though. My login pic was of myself and my cat. A few days ago, it was changed to one of myself only. I didn't do it deliberately. In fact, I didn't have a clue as to how and change it until I looked up after noticing the photo changed on its own. I changed it to a preset sunflower and it has stayed that way ever since. A glitch perhaps?
Thanks for all your help. It just occurred to me I should call Mac too since I did pay for an extended warranty and helpline!
