First do the following:
- Make sure that your computer is connected to the Internet.
- If you are using a firewall, go into its settings and allow the drwupsrv.exe update module, located in the folder containing the installed Dr.Web software, to access the Internet.
- If you access the Internet through a proxy server that requires authentication with a username and password, go to the settings and specify the proxy server’s address and port, and the username and password for it. To do this, right-click on the Dr.Web icon in the notification area, and select Tools –> Settings. In the next window, go to the Proxy server tab and configure the proxy server settings.
If after trying the above, you are still experiencing difficulties, please contact the Doctor Web technical support service and describe in detail how your computer connects to the Internet (note: if a proxy server is involved, please specify whether authentication is required, and whether your browser or Dr.Web update module is configured to be used via the proxy server).
