Antivirus/Antispam for Windows x64

I would really appreciate if anyone has any reliable information concerning x64 antivirus or antispam programs, or if x32 antispam will at least work on MS Outlook Express. Thanks

 

AVG and EWIDO.

 

AVG doesn't work with x64, and Ewido is not free. I'm using free version of Avast antivirus, XP's own firewall (behind a hardware firewall) and Mozilla suite for browsing and email (has a good spam blocker). Also using spywareblaster and spybotS&D.

 

I want to thank both of you for your help, although I wish Sparrow's reply had come before I had downloaded AVG Free Version and found out that only the paid version worked on Windows XP x64, because I am now running the paid version of AVG. Oh well, live and learn, I am going to get the Mozilla Suite though since I have not found a decent Spam filter yet, using Spamihilator 0.9.9.9 it really stinks, not easy to train at all.
