Installing and Uninstalling

This section describes how to install and uninstall Dr.Web for UNIX Mail Servers, as well as how to obtain current updates and upgrade to a new version, if an earlier version of Dr.Web for UNIX Mail Servers is already installed on your computer.

Moreover, this section describes the procedure of custom installation and uninstallation of the Dr.Web for UNIX Mail Servers components (for example, to resolve errors that occurred during the operation of Dr.Web for UNIX Mail Servers or to get an installation with a limited function set) and configuration of advanced security subsystems (such as SELinux) that could be necessary for installation or operation of Dr.Web for UNIX Mail Servers.

To perform these procedures, superuser (root) privileges are required. To gain superuser privileges, use the su command to change the current user or the sudo command to run the specified command as another user.

Compatibility of Dr.Web for UNIX Mail Servers and anti-virus products of other developers is not guaranteed. Due to the fact that the installation of two anti-viruses on one machine can cause errors of the operating system and loss of important data, it is strongly recommended that you uninstall anti-virus products of other developers on your computer before the installation of Dr.Web for UNIX Mail Servers.

If your computer already has another Dr.Web anti-virus product installed from the universal package (.run), and you want to install one more Dr.Web anti-virus product (for example, you have Dr.Web for Linux installed from the universal package, and you want to install Dr.Web for UNIX Mail Servers in addition to it), it is necessary to make sure that the version of the already installed product is the same as the version of Dr.Web for UNIX Mail Servers to be installed. If the version of the product to be installed is newer than the installed product version, it is necessary, before installation, to upgrade the installed Dr.Web for UNIX Mail Servers to the version of the product you want to install additionally.

Dr.Web for UNIX Mail Servers can be installed on FreeBSD only from the universal package.
