Font changed to bold(verdana?). How do I change it back?

[Brian 321]

I cant stand this font, It just changed and now everything is bold. I also cant run a certain game because of it.

Is there a way I can change this back to the default font?

Is this in Windows? If so, what version of Windows?

Very odd. I think I have seen a virus do something like that before.
