Online Backup To Save Your Important Files

I am pissed! My computer has a virus. Really, right now I cannot get rid of it. Every time I try and use Google it redirects to a different website. The husband tried to get rid of it but it is still there. So I am very concerned that it will ruin my computer. I wish that we had an online backup to make sure that if my computer crashes completely then I can recover everything that I have. I would hate to lose all my pictures and stuff that I have saved over the years since I've been here in the US.
