I'm scanning first for viruses with clamav. After that I use the expensive SpamAssassin checks only on non virus mails. That's the order you prefere. I'm not sure that this is cheaper. I estimate roughly that I receive about 100 times more spam than viruses. That means that I'm scanning about 100 spam mails (that could already have been detected by SpamAssassin, and that still have to be checked by SpamAssassin anyway) for viruses just to block a single virus. This 100 to 1 ratio is also expensive.
