Antispam vs antivirus proxy

I’ve got Antispam 1.01 running on my XP Pro SP2 box after a few weeks of running Choicemail Free. Antispam is better because it handles multiple email accounts. So far, so good.
I thought I would also give Comodo AV (1.1b) a shot too. It installed fine (once I’d uninstall Spywareguard), but now the spam emails are coming though again even though antispam is enabled.
I presume this is because AV handles email scanning through its proxy server and is, therefore, bypassing, AS.
How can I make this work again?


PS Thunderbird functionality would be nice for importing addresses.
