Usual installation

Installing Dr.Web

1.If other anti-virus software is installed on your computer, the Installation Wizard informs you on incompatibility between Dr.Web and another anti-virus product and offers to remove it.


Before the installation starts, the Wizard checks if the installation file is the latest one. If a newer installation file exists, you will be offered to download it before the installation.

2.At this step, you are prompted to connect to Dr.Web cloud services that allow anti-virus components to use the newest information which is stored and updated on Doctor Web servers. This option is enabled by default. You can also specify whether Dr.Web Firewall should be installed or not.

3.To select components you want to install, specify the installation path and configure other settings, click Installation parameters. The option is meant for experienced users. If you want to use default installation settings, go to step 4.

On the first tab, you can specify the components you want to install.

On the second tab, you can change the installation path.

The last tab of the window allows you to enable the Update during installation option to download updates to virus databases and other program components. The tab also prompts you to create shortcuts to Dr.Web.

If necessary, specify proxy server parameters.

To save the changes, click OK. To close the window without saving the changes, click Undo.

4.Click Next. Please note that by clicking the Next button you accept the terms of the License agreement.

5.The Registration Wizard informs you that a license is required for Dr.Web operation. Do one of the following:

If a key file is present on the hard drive or removable media, click Specify path to an available valid key file and select the file in the open window. To change the path, click Browse and select another key file.

If you want to receive a key file during the installation, select Receive license during installation.

To continue installation without a license, select Receive license later. Updates are not available until you specify or obtain a key file.

Click Install.

6.If you specified a key file or received it during the installation and did not clear the Update during installation check box, the wizard updates virus databases and other Dr.Web components. Updating starts automatically and does not require any additional actions.

7.Restart your computer after the installation is complete.
