Help with fonts

How do I restore ie back to defaults fonts?My son was on earlier and now I can barly read the pages.

 

Tools>options>fonts>times new roman.

 

If you can't read the pages, I suggest this tip: While holding the "Ctrl" button, use the scroll wheel to zoom in and out..
I bet that's the whole problem.... If not, I'm not sure what your son did... ))

 

Thanx for both and I think it was the scroll that did the trick.
