Weird Font on Websites?

Okay, I've been having this problem for a little while and I don't understand why it is happening. Sometimes I will visit websites and the font below is being used on the site, throwing off the design and usability completely.

Anyone know why? I use Chrome as my main browser, but it still happens in Firefox. I'm on a Windows 7 laptop.



(weirdly the font is the one I installed when I rooted my Android phone)
