Debian Linux Security Advisory 1906-1 – Security support for clamav, an anti-virus utility for Unix, has been discontinued for the stable distribution (lenny) and the oldstable distribution (etch). Clamav Upstream has stopped supporting the releases in etch and lenny. Also, it is not easily possible to receive signature updates for the virus scanner with our released versions anymore. We recommend that all clamav users consider switching to the version in debian-volatile, which receives regular updates and security support on a best effort basis.
