Virus Databases Update

Dr.Web uses special virus databases to detect threats. These databases contain details and signatures of all viruses and malicious programs for devices running Android known by Doctor Web experts. Virus databases have to be regularly updated as new malicious programs appear every day. The application features a special option for updating virus databases over the internet.

In the centralized protection mode, you cannot update virus databases manually; updates are downloaded automatically from the centralized protection server. If the mobile mode is enabled on the server and the connection with the centralized protection server is lost, you can update the virus databases manually.

Update

The virus databases are updated via the internet several times a day automatically. If the virus databases have not been updated for more than 24 hours (for example, if the device is not connected to the internet), you should update them manually.

To check whether you need to update virus databases

1.On the Dr.Web main screen, tap Menu and select Virus databases.

2.In the pop-up window, you will see the virus database update status and when the virus databases were last updated. If the last update happened more than 24 hours ago, you should update virus databases manually.

To start the update

1.On the Dr.Web main screen, tap Menu and select Virus databases.

2.Tap Update.

It is recommended to update the virus databases as soon as you install the app so that Dr.Web can use the most up-to-date information about known threats. As soon as the Doctor Web anti-virus laboratory experts discover new threats, an update for virus signatures, behavior characteristics, and attributes is issued. In some cases, updates can be issued several times per hour.
