Mac Java Virus?(Exploit.Java.ByteVerify-1)

This was the first time i scanned my computer for viruses in a long time (maybe about 1 and a half year ago was the last time). I don't know why i havent scanned earlier

When i scanned(and deleted), i had 2 infected files, Im using ClamXav as my antivirus

/Users/"my name"/Library/Caches/Java/cache/javapi/v1.0/file/animan.class-4bb611a9-5fa0d313.class: Exploit.Java.ByteVerify-1 FOUND

/Users/"my name"/Library/Caches/Java/cache/javapi/v1.0/file/animan.class-79dc8d6d-364a35d0.class: Exploit.Java.ByteVerify-1 FOUND

I wasnt sure what this was so i did a quick google search, and this came up

I also wasnt sure how long i had these infected files on my computer, could have been weeks or months even.
Has anyone else know more information about this?
As you can tell im worried, since my parents log onto their accounts(banking accounts and such)

 

I was thinking of putting bootcamp(today actually), and lets say the infected file was on Leopard/OS X side...since its more of a windows virus, would it eventually reach onto the Windows side and execute at whatever it shall do? Also if i get a virus on Windows, would that affect the Leopard/OS X portion?
