I needed to upgrade Clamav-83 to 84 . After of do make, the clamav show me this error:

Said me: "You need POSIX threads to run Milter. Try adding -lpthread to the finallink line."

Ok. I add -lpthread in the last options

gcc -g -O2 -o clamd output.o cfgparser.o getopt.o memory.o misc.o options.o clamd.o tcpserver.o localserver.o session.o thrmgr.o server-th.o scanner.o others.o clamuko.o dazukoio_compat12.o dazukoio.o -L/usr/local/lib ../libclamav/.libs/libclamav.a -lz -lbz2

And it Worked.
