Installation via the command line

To install Dr.Web in the background mode, enter in the command line the executable file name with necessary parameters (they affect installation in the background mode, installation language, reboot after installation, and Dr.Web Firewall installation).

For example, to start background installation of Dr.Web with reboot after the process completes, execute the following command:

drweb-11.5-ss-win.exe /silent yes /reboot yes

Installation in wizard mode

To start usual installation, do one of the following:

•If you have the executable file, run it.

•If you have the original disk containing installation package, insert the disk into the CD/DVD drive. If autorun is enabled, the installation will start automatically. If autorun is disabled, run the autorun.exe file of the installation kit manually. The window opens and displays the autorun menu. Click Install.

At any installation step, before the wizard starts copying files to your computer, you can do the following:

•Return to the previous step by clicking Back.

•Go to the next step by clicking Next.

•Abort installation by clicking 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 free CureIt! utility by Doctor Web. You can download CureIt! from Doctor Web website: https://free.drweb.com/download+cureit+free/.

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: https://support.microsoft.com/en-us/help/17613/automatically-diagnose-and-fix-problems-with-windows-firewall.

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.
