That's rather old, worth trying a more current version.

That would suggest that RAV is the problem. Have you tried calling RAV from
MD directly and not using a separate milter?

Well, over a minute has elapsed between the MD milter being called and RAV
ending it's run. I would say that that is your problem. Try increasing the
timout, or switch the order in which you define the milters in sendmail.mc.
Now, IMO unless that's a large email a minute is a long virus scan. I use
amavis for my virus scanning and have both Sophos Sweep AND F-Prot called
from it. Even then it only took a minute to unpack and scan a 2.5 MB zip
that held 162 files totalling 18 MB.
Please DO NOT send me ANY email directly unless it's a privacy issue.
