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, which allow to perform checks 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.

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.

1.Scan the system using free 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). You can download the utility from Microsoft website:

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