Should be:

        {eq {$received_protocol}{scanned-ok}}

This is not correct either. See below for more.

A condition that might work (I haven't tested it):

    condition = ${if and {\
        {eq\
            {$received_protocol}\
            {scanned-ok}}\
        {eq\
            {${lookup mysql{SELECT checkvirus FROM users \
                            WHERE checkvirus='yes' AND username='$local_part' \
                            AND domain='$domain'}}}\
            {yes}}
        }{yes}{no}}
