I do the same here--never stay logged on anywhere. I close my accounts and reopen each and every time I use them. Not worth the trouble if someone hacks into your stuff.
A few years back I got a very bad virus, still have no clue how I could have picked it up since I only open mail from people I know. But my computer, crashed bed, everything froze ,and what a jumbled mess, I was very lucky to have my son reload everything for me...lost a few things but fortunately my pictures were shuffled around but all there intact.
