Updating of Virus Databases and Program Components

To detect malicious objects, Dr.Web products use virus databases that contain information about all known malicious programs. Regular updates of databases allow the detection of previously unknown viruses, blocking their distribution, and in some cases curing previously incurable infected files. Besides virus databases, Dr.Web software components and help documentation are updated as well.

For Dr.Web to update, you need a connection to the internet or to the update mirror (local or network folder), or to the Anti-virus network with at least one computer that has an update mirror set. Customizing of update source settings can be done in General Update. The details of customization of Dr.Web updating parameters is located in Update section.

Update relevance check

To check the relevance of virus databases and program components, open Dr.Web menu Dr.Web icon. If updates are relevant, the Update item is highlighted in green.
