Which antivirus are you thinking of using?
ClamAV works pretty well, though I'm not sure how to set it up in Evolution. That'd be more of a question whether Evolution allows filtering attachments with 3rd party plugins, though, because ClamAV claims to support KMail as a plugin just fine.
If all else fails, you can always setup getmail or fetchmail with a procmail filter for clamav. Or whatever other antivirus, for that matter.
