System Requirements

You can use Dr.Web for Linux on a computer that meets the following requirements:




Both 32-bit (IA-32, x86) and 64-bit (x86-64, x64, amd64) Intel platforms are supported.

Hard disk space

Minimum 512 MB of free disk space on a volume where the Dr.Web for Linux directories are located.


Linux for Intel x86/amd64 platform based on kernel ver. 2.6.37 or later, and using library glibc ver. 2.13 or later.

Tested Linux distributions are listed below.

On systems operating on 64-bit platforms, support of 32-bit applications must be enabled (probably, additional libraries must be installed for this, see below).


The following valid network connections:

An Internet connection to download updates for virus databases and anti-virus engine and to use the Dr.Web Cloud service (only if it is manually authorized by the user).

When operating in central protection mode, connection to the server on the network is enough; connection to the Internet is not required.

The product was tested on the following Linux distributions (32-bit and 64-bit):

Linux distribution name


Required additional libraries for 64-bit OS version





20, 21






12.04, 14.04, 14.10



5.11, 6.6, 7.1


Red Hat Enterprise Linux

5.11, 6.6, 7.1


SUSE Linux Enterprise Server

11 SP3, 12

Other Linux distributions that meet the above-mentioned requirements have not been tested for compatibility with Dr.Web for Linux but may be supported. If a compatibility issue occurs, contact technical support on the official website at

On Debian, Fedora, Mint, and Ubuntu, SpIDer Guard (see below) uses the fanotify monitoring interface by default. On CentOS and Red Hat Enterprise Linux, the component uses a special loadable kernel module, which is supplied completely assembled with the product.

If necessary, you can build a loadable module manually by using the supplied source codes for any GNU/Linux-based operating systems with kernel 2.6.x and newer.

Under SUSE Linux Enterprise Server, by default, SpIDer Gate conflicts with SuseFirewall2. A way to resolve this conflict is described in the Appendix "Known Errors", see how to resolve error x109.

Additional Packages

To enable Dr.Web for Linux operation in graphics mode and startup of the program for product installation and removal in graphics mode, X Window System graphics subsystem and any window manager is required. Moreover, for correct operation of the indicator for Ubuntu Unity desktop environment, the libappindicator1 library is also required.

For scheduled scanning, crond must be installed in the operating system.

To start the product installer or uninstaller, designed for the command line, in graphics mode, a terminal emulator (such as xterm, xvt, etc.) is required. To enable privileges elevation during installation or uninstallation, one of the following utilities is required: su, sudo, gksu, gksudo, kdesu, kdesudo.

For convenient work with Dr.Web for Linux in the command line, you can enable command auto-completion in the used command shell (if disabled).

If you encounter any problem with installation of additional packages and components, refer to User Manuals for the used distribution of the operating system.
