Unless you get it from an unreliable source, Furcadia shouldn't
have any malicious data with it.
My advice: get it from the site itself ( www.furcadia.com ).
I have never detected any malware being downloaded with
Furcadia. However, if there is any malware that comes with
Furcadia, any simple virus detection would be able to tell you.
My advice: Use Firefox to download anything.
