+
+  Many users report that after updating ClamAV to 1.0.0 clamd and
+  freshclam fails to start with integrity check error of
+  databases. According to the result of investigation it happens with
+  following conditions.
+
+  1. ClamAV is built on non-cleanroom environment (that is, neither
+     FreeBSD official ClamAV package is used nor the package is built
+     by user with poudriere).
+  2. math/tomsfastmath is installed in the system that ClamAV is
+     built.
+
+  So if the errror happens on you system, uninstall TomsFastMath first
+  and then rebuild and reinstall ClamAV. The problem should disappear.
