Do not go to Crunchyroll. The site has been compromised via some backend mean and redirects you to a crunchyroll page that will try to download a .exe file, which if downloaded/ran will insert a ton of malware into your computer's harddrive which will in turn pretty much ruin your PC for good.

Chances are database was not compromised so account related things should be fine, but once Crunchyroll gives an official statement a password change is still a good idea once everything's safe again, if you have an account there that you use.
