Dr.Web virus database updates are small, usually not exceeding 50-200 KB.
Dr.Web technologies enable the anti-virus to use one database entry to identify hundreds and even thousands of malicious files—including those that may be created by hackers in the future.
Fast updating even with low bandwidth. A special data compression algorithm is employed by Doctor Web to deliver updates as archived files and save traffic. Patch files are used to deliver minor additions and fixes for virus databases or program modules. This dramatically reduces the amount of data transferred.
Automatic and manual updates—the latter can be performed on computers that are not connected to the Internet.
Scheduled updates.
No machine reboots are needed. Automatic updating of the virus databases ensures that Dr.Web can withstand previously unknown threats immediately after retrieving new virus definitions.
Ready to confront new types of threats. To tackle new malware, virus databases and key anti-virus components, including drivers, must be updated regularly. In such cases, a system restart may be necessary. Doctor Web always releases updates promptly. To save traffic, you can configure Dr.Web to retrieve only virus database updates. However, this option is not recommended because it can enable intruders to bypass the protection even if the virus definitions are up-to-date.
Dr.Web's self-defence effectively resists malignant attempts to disrupt or disable updating.
Virus monitoring service
The Doctor Web virus monitoring service collects samples of malicious programs all over the Internet and creates antidotes and releases updates as soon as testing is complete—as often as several times per hour.
As soon as an update is released, users can retrieve it from several servers located at various points of the globe.
To avoid false positives, an update is tested over a huge number of uninfected files before it is released.
An intelligent system for adding related viruses allows new malware definitions to be added to the virus database automatically, which makes it possible to respond faster to malicious attacks.
