Updated to Yosemite, safari freezes and cannot type into word

Question

I updated to Yosemite and my Safari has been freezing, and MS word will not work, I cannot type into new documents. I can open them, I can type here (so the keyboard works), but I cannot type in word

Answer 1

Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
~/Library/Safari
Right-click or control-click the line and select
          Services ▹ Open
from the contextual menu.* A folder should open. Quit the application if it's running. Move all files in that folder with a name beginning in "History" to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the items you moved back where they were, overwriting the ones that may have been created in their place. Otherwise, delete the items you moved. If possible, restore them from a backup that predates the problem.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
