So my computer had a virus!!

For the last 10 days or so, I have had a virus.  It was an update thru windows or so it appeared.  I am not a techie, so I just reset all settings back to factory settings and I will start again.  SIGH, what a pain.  Now I have to find all the blogs I follow again, and reset all my passwords again.  What did we do with our days when computers did not crash and cause this kind of problems?
