Like making sure clamd doesn't get corrupt/incomplete db files, by locking db dir during update and using checksum.

It will print "ERROR: cvdinfo: Verification: MD5 verification error" when the checksum in incorrect.
Another method would be to put db files (can be .vcd or third party signatures, like the one from sanesecurity/MSRBL) on a separate directory, and run "clamscan -d /PATH/TO/DB/DIR /SOME/TEST/FILE". clamscan will exit with non-zero error value (50, I think) if the db file is corrupted.
