I'm scared one day that I will get a virus or something on my computer & will destroy it like my other one (which I hope will never happen again) I have tons of folders and documents such as picture,videos,programs,games, etc saved on my computer. Does anyone know where I can upload all this stuff & save it?

Get an external.

Buy a flash drive? They're only a few dollars.

Backup via an external drive.

An external hard drive.
