Well heres how I did it... Linux box running fetchmail as a daemon to get the mail from the pop accounts, fetchmail forwards on to sendmail running on the box itself. MailScanner (www.mailscanner.info) to scan the email (with clamav and bitdefender, both of which are free in at least one sense of the word). sendmail then delivers the mail to local accounts and courier-imap lets the users collect them using IMAP. If you don't want to create accounts for each user then you might like to think about something like cyrus IMAP which (I think) doesn't require accounts on the server (but IIRC is rather more tricky to set up) - it was a no-brainer for me as my users (family, this is my home setup - I use MailScanner as a relay to exchange at work) already had shell accounts. There are other choices too, such as AMavis and clamav-milter, however what is commonly seen as the chief advantage of them (as milters) - being able to refuse to accept a mail, rather than reject it later - is a non issue in this instance because both your ISP and fetchmail have already accepted it.
