To install the program

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 the first step of installation process, you are prompted to connect to Dr.Web cloud services, that allow scanning using the newest information on threats. The information is updated in real-time mode. The option is enabled by default. You can also specify whether Dr.Web Firewall should be installed or not.

The third tab of the window allows you to enable the Update during installation option to download updates to virus databases and other program components. Enable the Enable compatibility with screen readers option to use such screen readers as, for example, JAWS and NVDA for reading loud the information on Dr.Web interface elements. This option makes Dr.Web interface accessible for disabled people. The tab also prompts you to create shortcuts to Dr.Web.

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

BFE service error while installing Dr.Web

Several Dr.Web components require the BFE (Base Filtering Engine Service) running. In case this service is absent or damaged, the installation of Dr.Web will not be possible. The damage or the absence of BFE service may indicate the presence of security threats on your computer.

If the attempt of Dr.Web installation has ended with error, do the following:

1.Scan the system using CureIt! utility by Doctor Web. You can download CureIt! from Doctor Web website:

2.Restore BFE service. To do this, you can use the Windows firewall recovery utility (for Windows 7 and later).

3.Run Dr.Web installation wizard and perform the installation according the instruction described above.

If the problem continues to appear, address to Doctor Web technical support.
