A good anti-virus application can detect viruses. Deleting an infected file that may contain important information is one thing, but restoring the file to its original “healthy” state is entirely another.

Cures Viruses

  • The Dr.Web anti-virus functions on infected computers; its exceptional resistance to viruses makes it stand out among anti-viruses.
  • Dr.Web has the highest success rate in the industry for curing active infections
  • There is no need to cure a system prior to installing Dr.Web; this is due to the product’s unique technologies for scanning memory processes and its outstanding ability to neutralize active infections.
  • High probability to launch a scanning process in the infected system even from a remote data-storage device without installation (e.g. from a USB flash drive)



Dr.Web is immune to any attempts by malicious programs to disrupt its operation. Dr.Web SelfPROtect is the unique anti-virus component that maintains the anti-virus’ security.

  • Dr.Web SelfPROtect is implemented as a driver that operates on the lowest system level. The driver can’t be stopped or unloaded without a system reboot.
  • Dr.Web SelfPROtect restricts access to a network, files and folders, certain branches of the Windows Registry and removable data-storage devices on the system driver level and protects the software from anti-antiviruses aiming to disrupt the operation of Dr.Web.
  • Some anti-viruses modify the Windows kernel through intercepting interrupts, changing vector tables or using other undocumented features. This may have a negative impact on the stability of a system and pave new ways for malicious programs to get into a system. At the same time, Dr.Web SelfPROtect maintains security of the anti-virus and doesn’t interfere with routines of the Windows kernel.
  • New! Automatic restoring of anti-virus modules

Unique Engine Features

  • Scan of archived files at any nesting level.
  • Reliably detects packed objects regardless of whether or not Dr.Web recognizes the compression format and their detailed analysis aimed at exposing hidden threats.
  • Leader in detecting and neutralizing complex rootkits.
  • Intelligent memory scan technologies allow viruses to be blocked in the RAM before replicating themselves to the hard drive, making it less likely for malware to exploit the vulnerability of a third-party application or the operating system.
  • Dr.Web can detect and neutralize viruses that can be found only in RAM and do not exist as files on disks, e.g. Slammer or CodeRed.

Detection Of Unknown Threats

  • FLY-CODE is a unique universal decompression technology enabling Dr.Web to unpack data that has been compressed with unknown packers.
  • The cutting-edge, non-signature scan technology Origins Tracing™ ensures the high probability that viruses unknown to Dr.Web will be detected.
  • The heuristic analyzer, whose analyses are based on criteria typical of various groups of malicious programs, detects most known threats.

Always up-to-date

  • Updating over the Internet, whether automatically or according to a schedule, doesn’t require user interference. Updating can also be launched manually.
  • Updating is very quick even if a slow Internet connection is used.
  • Updating servers are always available.
  • Updates can be retrieved from an HTTP server.
  • In most cases, there is no need to reboot the system to complete updating; Dr.Web starts using the updated modules and latest virus definitions right away
  • Updates are small (50-200KB).
  • To save traffic the anti-virus can be set to update virus databases only However, enabling this option is not recommended. To counter the latest threats, Dr.Web undergoes constant refinement. New features are incorporated in updated modules of an anti-virus package and are downloaded from Doctor Web's server automatically during regular updating sessions.
  • You can also reduce traffic by downloading updates as archived files A special data-compression algorithm used by Doctor Web allows reducing size of downloaded updates. Patch files are used to deliver minor additions and fixes for virus database or program modules. The special compression algorithm applied to such patches dramatically reduces the amount of transferred data.

Virus monitoring service

  • The Doctor Web virus monitoring service collects samples of malicious programs all over the Internet to create antidotes and release updates as soon as analyses are completed — 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.
  • The intelligent system automatically adds entries for similar viruses into the database, ensuring the prompt neutralization of emerging threats.
