I don't see how there could be.  It's not just that if detecting Sobig
were completely easy and reliable, then it wouldn't be a problem.
(For example see recent the long sad story in (I think) the RISKS
digest about the university that deleted Sobig mail messages).  It's
more that DCC clients aren't in that business.

If you do have a way to detect Sobig, then why not wrap it into a script
that deletes or moves asside the objectionable log files?
Why can't something elaborated from this do the job?

    find /var/dcc/log /var/dcc/userdirs -newer marker -name 'msg.*'  \
      xargs grep -l whatever | xargs -n 1  /bin/rm
    touch marker

(eg. some versions of xargs can be used to better effect with rm)
