need free anti key logger

Someone tried to hack my financial site and I guess I need a good free anti key logger. I use Alvira anti virus and was using spy shelter until I bought a new computer that has windows 8 (64 bit) and the free version is just for 32 bit. Any suggestions would be appreciated.

 

I found two anti keylogger softwares and while they don't detect keyloggers like Spyshelter did, they encrypt your keystrokes so a keylogger can't decipher what you are typing. One's name is Zemana Antilogger free and the other is KeyScrambler Personal Free. BTW, I misspelled my anti virus in my original post, it's Avira. Anyway, just thought I'd share what I had found, here is the site:
