Windows 7 IE text appears in italic

[Epic]

My browser has randomly started to display most text in italic. Someone said to delete some fonts and reinstall them, but when I try it, it says the fonts are protected. Could someone please help me with this?

EDIT: Solved by downloading and reinstalling the Arial font.
