Re-install?

Reinstall win7? I'm really looking for a way to preserve all my data, unless im mistaken, and that does keep all the data. And, I don't have a disk, it came preinstalled on my laptop.

Yes, I have an external drive, if I backup, will i be able to restore the computer, using that backup, to the state it is currently in whenever I want?

Yes, I ran all the scans, one thing I noted though, was that 7 threats were found and fixed by malwarebytes in safemode, even though I scanned earlier not in safe mode.
