If you click here you'll find a nice listing of compatible freeware options. All listed are compatible with Vista x64 unless otherwise noted. AVG Antispyware isn't listed there yet, but both AVG offerings are fully compatible.
Hope this helps,

Are AVG free antivirus and spyware Vista 64 compatible? Also can someone point me in the right direction for security protection for 64 bit Vista. Thanks in advance.
