Installing Dr.Web anti-virus on CentOS 7 OS

The personal installation package includes connection parameters and workstation authorization settings for the Dr.Web Server. To obtain the distribution, submit a request to technical support via the ticketing system.

To connect to the Dr.Web Server in the Cloud4U cloud, you must add a network interface connected to the drweb_network to the virtual machine being protected. This is also done by submitting a request to technical support via the ticketing system. Additionally, any previously installed antivirus software must be removed (if applicable).

All operations must be performed under the root account.

Step 1: Preparing the OS

Log in to the OS by entering the root username and password.

In CentOS 7SELinux must be disabled beforehand. To do this, edit the file located at /etc/selinux/config and set:

In the editor, change the SELINUX value to disabled as shown below:

After making the change, press Ctrl+X to exit the editor. A prompt will appear at the bottom of the screen asking whether to save the changes:

To save the changes, press Y, then Enter. The editor will then ask where to save the file (either the same file or a new name).

Leave the filename unchanged and press Enter. The editor will display a confirmation of the saved lines and return you to the console.

After applying these changes, reboot the OS by running:

Step 2: Installing Required Libraries

After rebooting, log in again.

Install additional libraries with the following command:

Wait for the download and installation to complete. The process is finished when you see "Complete!" and return to the console.

Step 3: Copying and Installing the Dr.Web Distribution

Copy the previously obtained Dr.Web distribution to the machine. If the file is on a network share, use wget with the appropriate path.
Example (if the file drweb-av-linux-amd64.run is on an FTP server):

Wait for the download to complete. You will see a confirmation message like this:

By default, wget saves the file in the user's home directory. Verify the downloaded file with:

Make the distribution file executable using chmod:

(If the file has a different name or path, adjust the command accordingly.)

Run the antivirus installer:

At the first installer prompt, answer "YES" (in uppercase).

Next, you will be asked to review and accept the license agreement.

  • Scroll through the agreement using the Space key.

  • At the end, type "yes" (lowercase) and press Enter.

  • Wait for the installation to complete, then reboot the OS again:

The installation process is now complete.
